Next should come device, options, and hints lines in that 27# order. All device and option lines must be described by a comment that 28# doesn't just expand the device or option name. Use only a concise 29# comment on the same line if possible. Very detailed descriptions of 30# devices and subsystems belong in man pages. 31# 32# A space followed by a tab separates 'options' from an option name. Two 33# spaces followed by a tab separate 'device' from a device name. Comments 34# after an option or device should use one space after the comment character. 35# To comment out a negative option that disables code and thus should not be 36# enabled for LINT builds, precede 'options' with "#!". 37# 38 39# 40# This is the ``identification'' of the kernel.

Details of the exact nature of the bug are sketchy, but some can be 2121# found at https://forum.openwrt.org/viewtopic.php?pid=70060 on pages 4, 5 and 2122# 6. This option enables this workaround. There is a performance penalty 2123# for this work around, but without it things don't work at all. The DMA 2124# from the card usually bursts 128 bytes, but on the affected CPUs, only 2125# 4 are safe. 2126options AH_RXCFG_SDMAMW_4BYTES 2127#device ath_ar9160 # AR9160 chips 2128#device ath_ar9280 # AR9280 chips 2129#device ath_ar9285 # AR9285 chips 2130device ath_rate_sample # SampleRate tx rate control for ath 2131device bwi # Broadcom BCM430* BCM431* 2132device bwn # Broadcom BCM43xx 2133device ral # Ralink Technology RT2500 wireless NICs. 2134 2135# Use "private" jumbo buffers allocated exclusively for the ti(4) driver. 2136# This option is incompatible with the TI_JUMBO_HDRSPLIT option below. 2137#options TI_PRIVATE_JUMBOS 2138# Turn on the header splitting option for the ti(4) driver firmware.
