Subject: qede: populate supported link modes maps on module init
Patch-mainline: v5.9-rc1
Git-commit: 1d4e4ecccb114449454592e24ad790e20f397c05
References: jsc#SLE-15143
Simplify and lighten qede_set_link_ksettings() by declaring static link
modes maps and populating them on module init. This way we save plenty
of text size at the low expense of __ro_after_init and __initconst data
(the latter will be purged after module init is done).
