Subject: meta-flow: Fix mf_get_mask() bug for IPv6 flow label.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff_plain;h=465d9a8fe680218cfd9254c312792e50349f9cd5

meta-flow: Fix mf_get_mask() bug for IPv6 flow label.

Commit 32455024 (OXM: Allow masking of IPv6 Flow Label) made the flow label
maskable but did not update mf_get_mask() accordingly.
