vhost: fix crash when exceeding file descriptors
Protect against DPDK crash when allocation of listen fd >= 1023.
For events on fd:s >1023, the current implementation will trigger
an abort due to access outside of allocated bit mask.
Corrections would include:
* Match fdset_add() signature in fd_man.c to fd_man.h
* Handling of return codes from fdset_add()
* Addition of check of fd number in fdset_add_fd()
The rationale behind the suggested code change is that,
fdset_event_dispatch() could attempt access outside of the FD_SET
bitmask if there is an event on a file descriptor that in turn
looks up a virtio file descriptor with a value > 1023.
Such an attempt will lead to an abort() and a restart of any
vswitch using DPDK.

The array used as source buffer in virtio_xmit_cleanup (free) is a

in rte_memcpy() implementation, there a code piece as following:
if (size > 256) {

The compiler traces the array all through the call stack and knows the
size of array is 128 and generates a warning on above [1] which tries to
access beyond byte 128.
But unfortunately it ignores the "(size > 256)" check.
Giving a hint to compiler that variable "size" is related to the size of

net/enic: fix removing old MAC address when setting new one
enic_set_mac_address() meant to remove the old MAC address before

net/enic: fix setting MAC address when a port is restarted
enic_disable() removed the MAC address when a port was shut down but
enic_enable() didn't add the MAC address back when the port was
started again. Move where we set the MAC address for the adapter from
enic_setup_finish() to a enic_enable() so that port restarting works
properly.

net/mlx5: fix crash in Rx
Fixed issue could occur when Mbuf starvation happens in a middle of
reception of a segmented packet. In such a situation, the PMD has to
release all segments of that packet. The end condition was wrong
causing it to free an Mbuf still handled by the NIC.

net/mlx5: fix packet type and offload flags on Rx
In mlx5 rx function, the packet_type and ol_flags mbuf fields are not
properly initialized when no rx offload feature is enabled (checksum, l2
tun checksum, vlan_strip, crc). Thus, these fields can have a value
different of 0 depending on their value when the mbuf was freed.
This can result in an incorrect application behavior if invalid
ol_flags/ptype are set, or memory corruptions if IND_ATTACHED_MBUF is
set in ol_flags.

net/enic: fix resource check failures when bonding devices
The enic PMD was using the same variables in the enic structure to
track two different things. Initially rq_count, wq_count, cq_count,
and intr_count were set to the values obtained from the VIC adapters
as the maximum resources allocated on the VIC, then in
enic_set_vnic_res(), they were set to the counts of resources actually
used, discarding the initial values. The checks in enic_set_vnic_res()
were technically incorrect if it is called more than once on a port,
which happens when using bonding, but were harmless in practice as the
checks couldn't fail on the second call.
The enic rx-scatter patch misunderstood the subtleties of
enic_set_vnic_res(), and naively added a multiply by two to the
rq_count check. This resulted in the rq_count check failing when
enic_set_vnic_res() was called a second time, ie when using bonding.
This patch adds new variables to the enic structure to track the
maximum resources the VIC is configured to provide so that the
information isn't later lost and calls to enic_set_vnic_res() do
the expected thing.
