[dpdk-dev] [PATCH] net/bond: change link status check to no-wait

[Declan Doherty <declan.doherty@intel.com>]

In the 802.3ad periodic callback function the link status of all slaves
is checked using rte_eth_link_get function. Depending on the slave 
device this function can block for up to 9 seconds and therefore
could cause issues with the LACP Daemon state machine and control
patches handling. This patch changes to the no-wait version of
the link get function.

Fixes: 46fb4368 ("bond:add mode 4")
