ixgbe patch for link status updates
An x550 with SFP+ interfaces attached to some switches can
have problems bringing the port up.
After configuring the link, there is a wait for 500 ms for
the link to come up. Some switches don't bring their ports up
that quickly. So the link is never observed to come up and is
reconfigured again the next time dpdk_update_link_state() is
called. Subsequent attempts time out also indefinitely.
Instead of waiting through 5 iterations of a 100 ms delay, wait
through 10 iterations. The i40e PMD does this when updating
link status.
This issue & patch will be reported to Intel so this or
some better solution can be applied upstream in the future.
