1) Don't exceed the drivers own hardcoded TX inline limit.
The blueflame register size can be much greater than the hardcoded limit
for inlining. Make sure we don't exceed the drivers own limit, because this
also means that the maximum number of TX fragments becomes invalid and
then memory size assumptions in the TX path no longer hold up.
2) Make sure the mlx5_query_min_inline() function returns an error code.
3) Header inlining is required when using TSO.
4) Catch failure to compute inline header size for TSO.
5) Add support for UDP when computing inline header size.
6) Fix for inlining issues with regards to DSCP.
Make sure we inline 4 bytes beyond the ethernet and/or
VLAN header to workaround a hardware bug extracting
the DSCP field from the IPv4/v6 header.

Query the minimal inline mode supported by the card.
When creating a send queue, cache the queried mode and optimize the transmit
if no inlining is required. In this case, we can avoid touching the headers
cache line and avoid dirtying several more lines by copying headers into
the send WQEs. Also, if no inline headers are used, hardware assists in
the VLAN tag framing.

This patch adds the missing pieces needed for device setup using the
mlx5en driver inside a virtual machine which is providing hardware
access through SR-IOV.

include the following list of changes:
- Added eswitch ACL table management
Introduce API for managing ACL table.
This API include the following features:
1) vlan filter - for VST/VGT+ support.
2) spoofcheck.
3) robust functionality to allow/drop general untagged/tagged traffic.
4) support for both ingress and egress ACL types.
- Added loopback filter to the vacl table.
- Added multicast list set in the vPort context
- Added promiscuous mode set in the vPort context
- Set the vlan list in vPort context
1) Check caps if VLAN list is not longer than FW supports
2) Set MODIFY_NIC_VPORT_CONTEXT command
- Changed MLX5_EEPROM_MAX_BYTES from 48 to 32 so that a single EEPROM
reading cannot cross the 128-byte boundary. Previously reading the
MCIA register was done in batches of 48 bytes. The third reading
would then by-pass the 127th byte, which means that part of the low
page and part of the high page would be read at the same time, which
created a bug:
1st: 0-47 bytes
2nd: 48-95 bytes
3rd: 96-143 bytes

Differential Revision: https://reviews.freebsd.org/D4411
from Mellanox Technologies. The current driver supports ethernet
speeds up to and including 100 GBit/s. Infiniband support will be
done later.
The code added is not compiled by default, which will be done by a
separate commit.
