Subject: [PATCH] dpaa2-eth: make the array faf_bits static const, makes object smaller
Date: Sun,  1 Aug 2021 16:22:09 +0100	[thread overview]
Message-ID: <20210801152209.146359-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

Don't populate the array faf_bits on the stack but instead it
static const. Makes the object code smaller by 175 bytes.

Before:
   text  data   bss     dec   hex filename
   9645  4552     0   14197  3775 ../freescale/dpaa2/dpaa2-eth-devlink.o

After:
   text  data   bss     dec   hex filename
   9406  4616     0   14022  36c6 ../freescale/dpaa2/dpaa2-eth-devlink.o

(gcc version 10.2.0)
