I've reported this several times over the last two years, but there's been no
reply and no change to the ixgbe driver.
Specifically, calling rte_eth_link_get_nowait() on FreeBSD does, in fact, wait
for link-up which causes unexpected and long delays.
I suggest removing the line from ixgbe_dev_link_update_share() that forces
"wait" to be set on FreeBSD. Would someone be willing to commit this, please?
Thanks,
