Add support for reading advanced diagnostic counters.

By default reading the diagnostic counters is disabled. The firmware
decides which counters are supported and only those supported show up
in the dev.mce.X.diagnostics sysctl tree.

To enable reading of diagnostic counters set one or more of the
following sysctls to one:

dev.mce.X.conf.diag_general_enable=1
dev.mce.X.conf.diag_pci_enable=1

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.
