Details of the exact nature of the bug are sketchy, but some can be 1986bc391cb2SWarner Losh# found at https://forum.openwrt.org/viewtopic.php?pid=70060 on pages 4, 5 and 1987bc391cb2SWarner Losh# 6. This option enables this workaround. There is a performance penalty 1988bc391cb2SWarner Losh# for this work around, but without it things don't work at all. The DMA 1989bc391cb2SWarner Losh# from the card usually bursts 128 bytes, but on the affected CPUs, only 1990bc391cb2SWarner Losh# 4 are safe. 1991bc391cb2SWarner Loshoptions AH_RXCFG_SDMAMW_4BYTES 1992390cee87SJohn Baldwin#device ath_ar9160 # AR9160 chips 1993390cee87SJohn Baldwin#device ath_ar9280 # AR9280 chips 199458c4a5a1SRui Paulo#device ath_ar9285 # AR9285 chips 1995390cee87SJohn Baldwindevice ath_rate_sample # SampleRate tx rate control for ath 1996390cee87SJohn Baldwindevice bwi # Broadcom BCM430* BCM431* 1997eb5ef23cSWeongyo Jeongdevice bwn # Broadcom BCM43xx 1998d1f25d5dSBernhard Schmidtdevice malo # Marvell Libertas wireless NICs. 1999d1f25d5dSBernhard Schmidtdevice mwl # Marvell 88W8363 802.11n wireless NICs. 2000778eefa4SJohn Baldwindevice mwlfw 2001390cee87SJohn Baldwindevice ral # Ralink Technology RT2500 wireless NICs. 2002b38b13d8SKevin Lodevice rtwn # Realtek wireless NICs 2003b38b13d8SKevin Lodevice rtwnfw 2004390cee87SJohn Baldwin 200510a4360cSPyun YongHyeon# Use sf_buf(9) interface for jumbo buffers on ti(4) controllers. 200610a4360cSPyun YongHyeon#options TI_SF_BUF_JUMBO 200798cb733cSKenneth D.
