From ed117aa1e9dc9cc0cbcfa6faa831bee2601d6b2b Mon Sep 17 00:00:00 2001 From: Mark Starovoytov Date: Wed, 25 Mar 2020 15:52:46 +0300 Subject: [PATCH] net: atlantic: add XPN handling This patch adds XPN handling. Our driver doesn't support XPN, but we should still update a couple of places in the code, because the size of 'next_pn' field has changed.
