| H A D | mlx5_ib_cq.c | 50e3ba10 Thu Mar 08 16:27:31 GMT 2018 Hans Petter Selasky <hselasky@FreeBSD.org> Set correct SL in completion for RoCE in mlx5ib(4).
There is a difference when parsing a completion entry between Ethernet
and IB ports. When link layer is Ethernet the bits describe the type of
L3 header in the packet. In the case when link layer is Ethernet and VLAN
header is present the value of SL is equal to the 3 UP bits in the VLAN
header. If VLAN header is not present then the SL is undefined and consumer
of the completion should check if IB_WC_WITH_VLAN is set.
While that, this patch also fills the vlan_id field in the completion if
present.
