ixgbe: Don't priority tag control frames in DCB mode
Certain types of control packets (LLDP, LACP, etc.) are not supposed to have a
priority tag or vlan tag inserted. Ixgbe driver is currently priority
tagging everything (if packet is not on a VLAN interface).
This patch modifies DCB mode, so that packets marked with skb priority
TC_PRIO_CONTROL are not priority tagged. It also transmits these packets on
the highest priority traffic class.
Programs (like dcbd) can set the skb priority using a socket option. Or, a tc
filter can be configured to set the priority value. Using the value
TC_PRIO_CONTROL (7) has the benefit that it is already defined in the kernel,
and the bonding LACP code already sets the skb->priority field to this value.
