Subject: [PATCH net v2] net: txgbe: fix the issue of TX failure

There is a occasional problem that ping is failed between AML devices.
That is because the manual enablement of the security Tx path on the
hardware is missing, no matter what its previous state was.

Fixes: 6f8b4c01a8cd ("net: txgbe: Implement PHYLINK for AML 25G/10G devices")
