From e688bdb7099c59c58ae231c6b87e42fb0a7d46bc Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Sun, 1 Aug 2021 16:12:05 +0100 Subject: [PATCH] cxgb4: make the array match_all_mac static, makes object smaller Don't populate the array match_all_mac on the stack but instead it static const. Makes the object code smaller by 75 bytes.
