Subject: [PATCH 13/22] treewide: Change misleading 'addr_ll' name
Date: Fri, 16 Aug 2024 15:39:54 +1000 [thread overview]
Message-ID: <20240816054004.1335006-14-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20240816054004.1335006-1-david@gibson.dropbear.id.au>
c->ip6.addr_ll is not like c->ip6.addr. The latter is an address for the
guest, but the former is an address for our use on the tap link. Rename it
accordingly, to 'our_tap_ll'.
Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
