net/enic: extend flow director support for 1300 series
1300 series Cisco adapter firmware version 2.0(13) for UCS
C-series servers and 3.1(2) for blade servers supports more
filtering capabilities. The feature can be enabled via Cisco
CIMC or USCM with the 'advanced filters' radio button. When
enabled, the these additional flow director modes are available:
RTE_ETH_FLOW_NONFRAG_IPV4_OTHER
RTE_ETH_FLOW_NONFRAG_IPV4_SCTP
RTE_ETH_FLOW_NONFRAG_IPV6_UDP
RTE_ETH_FLOW_NONFRAG_IPV6_TCP
RTE_ETH_FLOW_NONFRAG_IPV6_SCTP
RTE_ETH_FLOW_NONFRAG_IPV6_OTHER
Changes:
- Detect and set an 'advanced filters' flag dependent on the adapter
capability.
- Implement RTE_ETH_FILTER_INFO filter op to return the flow types
available dependent on whether advanced filters are enabled.
- Use a function pointer to select how filters are added to the adapter:
copy_fltr_v1() for older firmware/adapters or copy_fltr_v2() for
adapters which support advanced filters.
- Apply fdir global masks to filters when in advanced filter mode.
- Update documentation.

log: respect logger configured before EAL init
Before this patch, application-specific loggers could not be
installed before rte_eal_init completed (the initialization process
called rte_openlog_stream, overwriting any previously installed
logger). This made it impossible for an application to capture the
initial log messages generated during rte_eal_init. This patch changes
initialization so that information from a previous call to
rte_openlog_stream is not lost. Specifically:
* The default log stream is now maintained separately from an
application-specific log stream installed with rte_openlog_stream.
* rte_eal_common_log_init has been renamed to eal_log_set_default,
since this is all it does. It no longer invokes rte_openlog_stream; it
just updates the default stream. Also, this method now returns void,
rather than int, since there are no errors.
This patch also removes the "early log" mechanism and cleans up the
log initialization mechanism:
* The default log stream defaults to stderr on all platforms if
eal_log_set_default hasn't been invoked (Linux used to use stdout
during the first part of initialization).
* Removed rte_eal_log_early_init; all of the desired functionality can
be achieved by calling eal_log_set_default.
* Removed lib/librte_eal/bsdapp/eal/eal_log.c: it contained only one
function, rte_eal_log_init, which is not needed or invoked for BSD.
* Removed declaration for eal_default_log_stream in rte_log.h (it's now
private to eal_common_log.c).
* Moved call to rte_eal_log_init earlier in rte_eal_init for Linux, so
that it starts using the preferrred log ASAP.

mbuf: add new Rx checksum flags
Following discussions in [1] and [2], introduce a new bit to
describe the Rx checksum status in mbuf.
Before this patch, only one flag was available:
PKT_RX_L4_CKSUM_BAD: L4 cksum of RX pkt. is not OK.
And same for L3:
PKT_RX_IP_CKSUM_BAD: IP cksum of RX pkt. is not OK.
This had 2 issues:
- it was not possible to differentiate "checksum good" from
"checksum unknown".
- it was not possible for a virtual driver to say "the checksum
in packet may be wrong, but data integrity is valid".
This patch tries to solve this issue by having 4 states (2 bits)
for the IP and L4 Rx checksums. New values are:
- PKT_RX_L4_CKSUM_UNKNOWN: no information about the RX L4 checksum
-> the application should verify the checksum by sw
- PKT_RX_L4_CKSUM_BAD: the L4 checksum in the packet is wrong
-> the application can drop the packet without additional check
- PKT_RX_L4_CKSUM_GOOD: the L4 checksum in the packet is valid
-> the application can accept the packet without verifying the
checksum by sw
- PKT_RX_L4_CKSUM_NONE: the L4 checksum is not correct in the packet
data, but the integrity of the L4 data is verified.
-> the application can process the packet but must not verify the
checksum by sw. It has to take care to recalculate the cksum
if the packet is transmitted (either by sw or using tx offload)
And same for L3 (replace L4 by IP in description above).
This commit tries to be compatible with existing applications that
only check the existing flag (CKSUM_BAD).

vhost: add dequeue zero copy
The basic idea of dequeue zero copy is, instead of copying data from
the desc buf, here we let the mbuf reference the desc buf addr directly.
Doing so, however, has one major issue: we can't update the used ring
at the end of rte_vhost_dequeue_burst. Because we don't do the copy
here, an update of the used ring would let the driver to reclaim the
desc buf. As a result, DPDK might reference a stale memory region.
To update the used ring properly, this patch does several tricks:
- when mbuf references a desc buf, refcnt is added by 1.
This is to pin lock the mbuf, so that a mbuf free from the DPDK
won't actually free it, instead, refcnt is subtracted by 1.
- We chain all those mbuf together (by tailq)
And we check it every time on the rte_vhost_dequeue_burst entrance,
to see if the mbuf is freed (when refcnt equals to 1). If that
happens, it means we are the last user of this mbuf and we are
safe to update the used ring.
- "struct zcopy_mbuf" is introduced, to associate an mbuf with the
right desc idx.
Dequeue zero copy is introduced for performance reason, and some rough
tests show about 50% perfomance boost for packet size 1500B. For small
packets, (e.g. 64B), it actually slows a bit down (well, it could up to
15%). That is expected because this patch introduces some extra works,
and it outweighs the benefit from saving few bytes copy.

updated only when the mbuf is consumed. Thus, we need use another var to

The right way to go is to remove the structure and move all those fields

Now, thanks to the ABI refactoring, it's never been a blocking issue

net/virtio: set MTU
Virtio interfaces do not currently allow the user to specify a particular
Maximum Transmission Unit (MTU). Consequently, the MTU of Virtio interfaces
is typically set to the Ethernet default value of 1500.
This is problematic in the case of cloud deployments, in which a specific
(and potentially non-standard) MTU needs to be set by a DHCP server, which
needs to be honored by all interfaces across the traffic path.To acheive
this Virtio interfaces should support setting of MTU.
In case when GRE/VXLAN tunneling is used for internal communication, there
will be an overhead added by the infrastructure in the packet over and
above the ETHER MTU of 1518. So to take care of this overhead in these
cases the DHCP server corrects the L3 MTU to 1454. But since virtio
interfaces was not having the MTU set functionality that MTU sent by the
DHCP server was ignored and the instance will still send packets with 1500
MTU which after encapsulation will become more than 1518 and eventually
gets dropped in the infrastructure.
By adding an additional 'set_mtu' function to the Virtio driver, we can
honor the MTU sent by the DHCP server. The dhcp server/controller can
then leverage this 'set_mtu' functionality to resolve the above
mentioned issue of packets getting dropped due to incorrect size.

app/testpmd: fix DCB configuration
An issue is found that DCB cannot be configured on ixgbe
NICs. It's said the TX queue number is not right.
On ixgbe the max TX queue number is not fixed, it depends
on the multi-queue mode.
This patch adds the device configuration before getting
info in the DCB configuration process. So the right info
can be got depending on the configuration.

app/testpmd: fix TSO with checksum engine
The commit that disabled TSO for small packets was broken during the
rebase. The problem is the IP checksum is not calculated in software if:
- TX IP checksum is disabled
- TSO is enabled
- the current packet is smaller than tso segment size
When checking if the PKT_TX_IP_CKSUM flag should be set (in case
of tso), use the local tso_segsz variable, which is set to 0 when the
packet is too small to require tso. Therefore the IP checksum will be
correctly calculated in software.
Moreover, we should not use tunnel segment size for non-tunnel tso, else
TSO will stay disabled for all packets.
