[PATCH v1 6/9] net/i40e: fix SCTP verification tag truncation in FDIR

[Anatoly Burakov]

The SCTP verification tag is a 32-bit field, but the FDIR SCTP node
stored its spec and mask in 16-bit variables, truncating the tag
programmed into the filter.

Fixes: 05432a6e4676 ("net/i40e: reimplement FDIR parser")
