Subject: igb: use EOPNOTSUPP instead of ENOTSUPP in igb_get_sset_count()
X-Git-Tag: v6.18-rc4~24^2~15^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bc73c5885c606f5e48dd4222eba0361fa0f146ca;p=thirdparty%2Flinux.git

igb: use EOPNOTSUPP instead of ENOTSUPP in igb_get_sset_count()

igb_get_sset_count() returns -ENOTSUPP when a given stringset is not
supported, causing userland programs to get "Unknown error 524".

Since EOPNOTSUPP should be used when error is propagated to userland,
return -EOPNOTSUPP instead of -ENOTSUPP.
