add some more BAR debugging logic. * Change the definition of ath_debug and ath_softc.sc_debug from int to uint64_t; * Change the relevant sysctls; * Add a new BAR TX debugging field; * Use this in if_ath_tx. This has been tested by using the sysctl program, which happily allows for fields > 32 bits to be configured.
