mlx5en: Add missing media types for 100GBit/s, 200Gbit/s and 400Gbit/s.

Make the mlx5e_mode_table[] array one dimensional, because there is only
one entry, 10G ER/LR, which share the same protocol bit.

This patch only adds support for basic sub-type distinguishing for the
extended protocol bits. Use verbose ifconfig eeprom output to get actual
media type.

Remove write only "connector_type" variable while at it.

Implement support for Differentiated Service Code Point, DSCP, in mlx5en(4).

The DSCP feature is controlled using a set of sysctl(8) fields under
the qos sysctl directory entry for mlx5en(4).

For Routable RoCE QPs, the DSCP should be set in the QP's address path.
The DSCP's value is derived from the traffic class.

Add support for per priority flow control, PFC, to mlx5en(4).

Add support for PFC and implement reading the per priority statistics
using the sysctl(8) interface. PFC is used together with VLAN priority
and can be enabled and disabled on a per priority basis.

Global pause frames and PFC are incompatible features and surrounding
logic has been added to warn the user about misconfiguration.

Update relevant mlx5core APIs for PFC configuration.
