When an AML40 port links up at 10G, DPDK reports the speed as 100M
instead of 10G. The 10G link status bit is not recognized in
txgbe_check_mac_link_aml40(), so any non-40G speed falls through to
the default case (UNKNOWN) which is then reported as 100M.
Add the 10G port status bit recognition, so a 10G link is reported
as 10G.
