Subject: [dpdk-dev] IXGBE VF: segfault in ixgbe_dev_link_update
Date: Wed, 10 May 2017 11:41:57 +0300	[thread overview]
Message-ID: <99629734.on6ryOyqmF@polaris> (raw)

Hello,

My application works with IXGBE VF 17.05-rc4.
After I shutdown switch port,
a call for rte_eth_link_get() crashes with SEGFAULT.
Apparently, ixgbe_dev_link_update() calls for non-existing in VF driver ixgbe_get_link_capabilities().

Is there a patch with get_link_capabilities() implementation for IXGBE VF I can use ?
or 
Can I safely disable call for ixgbe_get_link_capabilities() for VF ?

Regards,
Gregory
