Add support for CQE zipping. CQE zipping reduces PCI overhead by
coalescing and zipping multiple CQEs into a single merged CQE. The
feature is enabled by default and can be disabled by a sysctl.

Implementing this feature mlx5_cqwq_pop() has been separated from
mlx5e_get_cqe().

Update the mlx5 shared driver code to the latest version, which
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

Add mlx5 and mlx5en driver(s) for ConnectX-4 and ConnectX-4LX cards
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.
