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, and include 10G in the
default advertised speed mask in txgbe_dev_start() so a 10G link is
reported with the correct speed.
