| Subject: [PATCH] ixgbe: wait longer for link after fiber MAC setup |
| |
| 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") |
