Subject: [dpdk-stable] [PATCH] ixgbe: wait longer for link after fiber MAC setup
Date: Mon, 16 Jul 2018 11:36:04 -0500 [thread overview]
Message-ID: <20180716163604.31896-1-mgsmith@netgate.com> (raw)
After setting up the link on a fiber port, the maximum wait time for
the link to come up is 500 ms in ixgbe_setup_mac_link_multispeed_fiber().
On an x550 SFP+ port, this is often not sufficiently long for the link
to come up. This can result in never being able to retrieve accurate
link status for the port using rte_eth_link_get_nowait().
Increase the maximum wait time in ixgbe_setup_mac_link_multispeed_fiber()
to 1 s.
Bugzilla ID: 69
Fixes: f3430431abaf ("ixgbe/base: add SFP+ dual-speed support")
