app/testpmd: fix DDP package filesize detection

This issue was about passing unsigned argument where should be signed
number.
In reality this is about wrong usage of fseek and ftell to determine
filesize.
This patch is compliant to suggestions from FIO19-C:
"Do not use fseek() and ftell() to compute the size of a regular file"

net/qede/base: fix for VF malicious indication

IOV regression testing led to discovery of a minor issue + possibly race
in IOV flows:
 a. Malicious indications in VF-database on PF-side get cleared during
    FLR flows - but not when disabling SRIOV. At least in Linux if you
    disable IOV while having a malicious VF you wouldn't be able to
    clear the indication as driver would prevent from initializing it.
 b. Possible race during PF response to VF - the channel is made ready
    only after sending the rc via dmae to VF. It's possible due to
    context switch at end of DMAE [when releasing Mutex] that VF would
    start running and send another message prior to PF clearing the
    channel, making the FW consider that VF to be malicious.

This patch fixes that by
 - clearing the indication even if we're only going to disable VF
 - resetting the channel to ready before PF copies the rc to the VF, PF
   can then continue and send an additional message

gso: support TCP/IPv4 GSO

This patch adds GSO support for TCP/IPv4 packets. Supported packets
may include a single VLAN tag. TCP/IPv4 GSO doesn't check if input
packets have correct checksums, and doesn't update checksums for
output packets (the responsibility for this lies with the application).
Additionally, TCP/IPv4 GSO doesn't process IP fragmented packets.

TCP/IPv4 GSO uses two chained MBUFs, one direct MBUF and one indrect
MBUF, to organize an output packet. Note that we refer to these two
chained MBUFs as a two-segment MBUF. The direct MBUF stores the packet
header, while the indirect mbuf simply points to a location within the
original packet's payload. Consequently, use of the GSO library requires
multi-segment MBUF support in the TX functions of the NIC driver.

If a packet is GSO'd, TCP/IPv4 GSO reduces its MBUF refcnt by 1. As a
result, when all of its GSOed segments are freed, the packet is freed

gso: add Generic Segmentation Offload API framework

Generic Segmentation Offload (GSO) is a SW technique to split large
packets into small ones. Akin to TSO, GSO enables applications to
operate on large packets, thus reducing per-packet processing overhead.

To enable more flexibility to applications, DPDK GSO is implemented
as a standalone library. Applications explicitly use the GSO library
to segment packets. To segment a packet requires two steps. The first
is to set proper flags to mbuf->ol_flags, where the flags are the same
as that of TSO. The second is to call the segmentation API,
rte_gso_segment(). This patch introduces the GSO API framework to DPDK.

rte_gso_segment() splits an input packet into small ones in each
invocation. The GSO library refers to these small packets generated
by rte_gso_segment() as GSO segments. Each of the newly-created GSO
segments is organized as a two-segment MBUF, where the first segment is a
standard MBUF, which stores a copy of packet header, and the second is an
indirect MBUF which points to a section of data in the input packet.
rte_gso_segment() reduces the refcnt of the input packet by 1. Therefore,
when all GSO segments are freed, the input packet is freed automatically.
Additionally, since each GSO segment has multiple MBUFs (i.e. 2 MBUFs),
the driver of the interface which the GSO segments are sent to should
support to transmit multi-segment packets.

The GSO framework clears the PKT_TX_TCP_SEG flag for both the input
packet, and all produced GSO segments in the event of success, since
segmentation in hardware is no longer required at that point.

app/testpmd: enable the heavyweight mode TCP/IPv4 GRO

The GRO library provides two modes to reassemble packets. Currently, the
csum forwarding engine has supported to use the lightweight mode to
reassemble TCP/IPv4 packets. This patch introduces the heavyweight mode
for TCP/IPv4 GRO in the csum forwarding engine.

With the command "set port <port_id> gro on|off", users can enable
TCP/IPv4 GRO for a given port. With the command "set gro flush <cycles>",
users can determine when the GROed TCP/IPv4 packets are flushed from
reassembly tables. With the command "show port <port_id> gro", users can
display GRO configuration.

The GRO library doesn't re-calculate checksums for merged packets. If
users want the merged packets to have correct IP and TCP checksums,
please select HW IP checksum calculation and HW TCP checksum calculation
for the port which the merged packets are transmitted to.

lib/librte_vhost/iotlb.c:318:6: warning:
variable 'socket' is used uninitialized whenever
'if' condition is false [-Wsometimes-uninitialized]

This is a false positive, as the socket value will be initialized by the

However, this is not immediately obvious, and is perhaps a little fragile,
as it will break if other code using ret is subsequently added above the
call to get_mempolicy by someone unaware of this subtle dependency.
Therefore, we can fix the warning and making the code more robust by
