This is an initial work in progress to use the replacement bhnd bus code for devices which support it. * Add manpage updates for bhnd, bhndb, siba * Add kernel options for bhnd, bhndbus, etc * Add initial support in if_bwn_pci / if_bwn_mac for using bhnd as the bus transport for suppoted NICs * if_bwn_pci will eventually be the PCI bus glue to interface to bwn, which will use the right backend bus to attach to, versus direct nexus/bhnd attachments (as found in embedded broadcom devices.) The PCI glue defaults to probing at a lower level than the bwn glue, so bwn should still attach as per normal without a boot time tunable set. It's also not fully fleshed out - the bwn probe/attach code needs to be broken out into platform and bus specific things (just like ath, ath_pci, ath_ahb) before we can shift the driver over to using this. Tested: * BCM4311, STA mode * BCM4312, STA mode Submitted by: Landon Fuller <landonf@landonf.org> Differential Revision: https://reviews.freebsd.org/D6191
