Subject: [PATCH] mac80211: fix BUILD_BUG_ON() caused by misalignment on arm
Date: Mon, 03 Nov 2008 21:05:01 +0100 [thread overview]
Message-ID: <490F596D.9010307@openwrt.org> (raw)
On ARM alignment is done slightly different from other architectures.
struct ieee80211_tx_rate is aligned to word size, even though it only has 3
single-byte members, which triggers the BUILD_BUG_ON in
ieee80211_tx_info_clear_status
This patch marks the struct ieee80211_tx_rate as packed, so that ARM
behaves like the other architectures.
