Driver authors should be aware of the alignment requirements, but not everybody cares about the warning. This patch makes it depend on a new Kconfig symbol MAC80211_DEBUG_PACKET_ALIGNMENT which can be enabled regardless of MAC80211_DEBUG and is recommended for driver authors (only). This also restricts the warning to data packets so other packets need not be realigned to not trigger the warning. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
