[Intel-wired-lan] [PATCH iwl-net v1 1/3] igb: use EOPNOTSUPP instead of ENOTSUPP in igb_get_sset_count()

[Kohei Enju]

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.

Fixes: 9d5c824399de ("igb: PCI-Express 82575 Gigabit Ethernet driver")
