[dpdk-dev] net/avf: fix link autoneg value
Checks
Commit Message
Intention of the logic is:
If ETH_LINK_SPEED_FIXED is set in dev_conf, set link_autoneg to
ETH_LINK_FIXED, else set it to ETH_LINK_AUTONEG
ETH_LINK_SPEED_FIXED value is 1, and ETH_LINK_FIXED is 0;
Current logic is broken, fix it according above values.
Fixes: 48de41ca11f0 ("net/avf: enable link status update")

BTW, I saw the same issue on i40evf, will you also fix that?
Thanks
