> Subject: [PATCH] net/ice: fix flow type selection for FDIR
> 
> The FDIR parser will select ICE_FLTR_PTYPE_NONF_IPV4_OTHER as flow type
> for an IPv4 UDP flow with empty l4 matching field which is not correct.
> Same issues happens on all the combination between IPv4/IPv6 and
> UDP/TCP/SCTP cases
> 
> The patch fix all the wrong flow ptype selections.
> 
> Fixes: f5cafa961fae ("net/ice: add flow director create and destroy")
