Mechanically substitute flags from historic mbuf allocator with malloc(9) flags in sys/dev.

MFC r225941:

Fix an unaligned access issue; tidy up OFDM/DS rate decoding from the PLCP. This fixes a panic on PPC. Submitted by: novel Obtained from: OpenBSD, sys/dev/ic/bwi.c r1.89 MFC r226181: Update from OpenBSD: Include 0x4402 in the bbp id mapping table used on older devices. http://bcm-specs.sipsolutions.net/BackPlane agrees. Obtained from: OpenBSD, sys/dev/ic/bwi.c r1.88 MFC r226182: Fix an incorrect use of sizeof(). Obtained from: OpenBSD sys/dev/ic/bwi.c r1.87 MFC r228621: Fix some net80211 enum nits: - ic_vap_create() uses an ieee80211_opmode argument - ieee80211_rate2media() takes an ieee80211_phymode argument - ieee80211_plcp2rate() takes an ieee80211_phytype argument - cast to enum ieee80211_protmode and ieee80211_roamingmode to silence compiler warnings Submitted by: arundel@

Pull ieee80211_ratectl_node_init() calls from drivers into net80211.

This fixes hostap mode for at least ral(4) and run(4), because there is no sufficient call into drivers which could be used initialize the node related ratectl variables. MFC after: 3 days

Instead of using the AMRR ratectl algo as default for drivers which have

2010-11-06T18:17:20Z

the IEEE80211_C_RATECTL flag set, default to NONE for all drivers. Only if a driver calls ieee80211_ratectl_init() check if the NONE algo is still selected and try to use AMRR in that case. Drivers are still free to use any other algo by calling ieee80211_ratectl_set() prior to the ieee80211_ratectl_init() call. After this change it is now safe to assume that a ratectl algo is always available and selected, which renders the IEEE80211_C_RATECTL flag pretty much useless. Therefore revert r211314 and 211546.
