Subject: tg3: Remove 40BIT_DMA_LIMIT_BUG
X-Git-Tag: MMI-PSA29.97-13-9~18929^2~451^2~6
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=daf9a55387df8f429d1219bbdabba1ab33d2a479;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

tg3: Remove 40BIT_DMA_LIMIT_BUG

This patch removes the 40BIT_DMA_LIMIT_BUG flag.  There already exists a
flag for this purpose (TG3_FLAG_40BIT_DMA_BUG) and was already being
used in the correct spot.
