Details of the exact nature of the bug are sketchy, but some can be 2027bc391cb2SWarner Losh# found at https://forum.openwrt.org/viewtopic.php?pid=70060 on pages 4, 5 and 2028bc391cb2SWarner Losh# 6. This option enables this workaround. There is a performance penalty 2029bc391cb2SWarner Losh# for this work around, but without it things don't work at all. The DMA 2030bc391cb2SWarner Losh# from the card usually bursts 128 bytes, but on the affected CPUs, only 2031bc391cb2SWarner Losh# 4 are safe. 2032bc391cb2SWarner Loshoptions AH_RXCFG_SDMAMW_4BYTES 2033390cee87SJohn Baldwin#device ath_ar9160 # AR9160 chips 2034390cee87SJohn Baldwin#device ath_ar9280 # AR9280 chips 203558c4a5a1SRui Paulo#device ath_ar9285 # AR9285 chips 2036390cee87SJohn Baldwindevice ath_rate_sample # SampleRate tx rate control for ath 2037390cee87SJohn Baldwindevice bwi # Broadcom BCM430* BCM431* 2038eb5ef23cSWeongyo Jeongdevice bwn # Broadcom BCM43xx 2039d1f25d5dSBernhard Schmidtdevice malo # Marvell Libertas wireless NICs. 2040d1f25d5dSBernhard Schmidtdevice mwl # Marvell 88W8363 802.11n wireless NICs. 2041778eefa4SJohn Baldwindevice mwlfw 2042390cee87SJohn Baldwindevice ral # Ralink Technology RT2500 wireless NICs. 2043b38b13d8SKevin Lodevice rtwn # Realtek wireless NICs 2044b38b13d8SKevin Lodevice rtwnfw 2045390cee87SJohn Baldwin 204610a4360cSPyun YongHyeon# Use sf_buf(9) interface for jumbo buffers on ti(4) controllers. 204710a4360cSPyun YongHyeon#options TI_SF_BUF_JUMBO 204898cb733cSKenneth D.
