Subject: [PATCH v4 2/6] net/eth: Better describe _eth_get_rss_ex_dst_addr's offset argument
Date: Tue,  9 Mar 2021 19:27:05 +0100	[thread overview]
Message-ID: <20210309182709.810955-3-philmd@redhat.com> (raw)
In-Reply-To: <20210309182709.810955-1-philmd@redhat.com>

The 'offset' argument represents the offset to the ip6_ext_hdr
header, rename it as 'ext_hdr_offset'.
