Subject: ixgbe: Cleanup unneeded delay in ethtool test
Patch-mainline: v5.9-rc1
Git-commit: bb0967c04e8bed3428e4c54f925cdd1890f8d2c6
References: jsc#SLE-13706

There is a 4 seconds delay in ixgbe_diag_test() that is holding up other
ioctls such as SIOCGIFCONF that Oracle database applications use.
One of Oracle's product runs "ethtool -t ethX online" periodically for
system monitoring and that is impacting database applications that use
SIOCGIFCONF at that same time.

This 4 second delay was needed in out early 1GbE parts to give the PHY
time to recover from a reset.  This code was carried forward to the 10 GbE
driver even it was not needed for the supported PHYs in the ixgbe driver.
