[dpdk-dev] [PATCH] net/i40e: fix link up failure issue

2018-05-17 Thread Jeff Guo
In case of the known issue, that DPDK PHY config can't synchronous with kernel driver and firmware, this will result of the nic can't link up after rebind to the kernel driver. This patch propose to work around it by don't config PHY and don't set link down when stop device. Fixes: 6e145fcc754b ("

2018-05-15 Thread Jeff Guo
If don't enable auto negotiation when set PHY to be link down, will cause PHY can’t be Link up again in some case, this patch aim to fix this issue. When rebind to kernel driver, it can use ethtool to set auto negotiation and use ifconfig tool to link up the device. And for the case of PHY config
