net/mlx5e: Add ToS (DSCP) header rewrite support
Add support for rewriting of DSCP part of ToS field.
Next commands, for example, can be used to offload rewrite action:
OVS:
$ ovs-ofctl add-flow ovs-sriov "ip, in_port=REP, \
actions=mod_nw_tos:68, output:NIC"
iproute2 (used retain mask, as tc command rewrite whole ToS field):
$ tc filter add dev REP ingress protocol ip prio 1 flower skip_sw \
ip_proto icmp action pedit munge ip tos set 68 retain 0xfc pipe \
action mirred egress redirect dev NIC
