[dpdk-dev] [PATCH] ixgbe: extend the timer support to x550em

[dpdk-dev] [PATCH] ixgbe: extend the timer support to x550em

[Wenzhuo Lu]

An issue is found on x550em NICs, that ieee1588 is not working, the time
always be 0.
The root cause is the timer is only supported by x550, it's not extended
to x550em_x and x550em_a.

Fixes: a7740dc1303a("ixgbe: support new devices and MAC types")
