Author: adrian Date: Sat Jun 27 02:59:51 2020 New Revision: 362671 URL: https://svnweb.freebsd.org/changeset/base/362671 Log: [ath_hal] Add KeyMiss for AR5212/AR5416 series chips. This is a flag from the MAC that says the received packet didn't match a keycache slot. This isn't technically a problem as WEP keys don't match keycache slots (they're "global" keys), but it could be useful for tracking down CCMP decryption failures. Right now it's a no-op - it mirrors what the AR9300 HAL does and it just increments a counter. But, hey, maybe one day I'll use it for diagnosing keycache/CCMP decrypt issues.
