Subject: ath9k: fix a WEP crypto related regression
From: Felix Fietkau <[email protected]>
commit f88373fa47f3ce6590fdfaa742d0ddacc2ae017f upstream.
commit b4a82a0 "ath9k_hw: fix interpretation of the rx KeyMiss flag"
fixed the interpretation of the KeyMiss flag for keycache based lookups,
however WEP encryption uses a static index, so KeyMiss is always asserted
for it, even though frames are decrypted properly.
Fix this by clearing the ATH9K_RXERR_KEYMISS flag if no keycache based
lookup was performed.
