X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3799cf47e3497a472b05f88e7a52a14931597d78;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git bnx2x: Disable HC coalescing when setting timeout to zero. Problem reported by Flavio Leitner : When setting rx/tx coalescing timeout to the values less than 12 traffic was stopped. The FW supports coalescing in 12us granularity, and so value of less then 12 should be interpreted as disabling coalescing Signed-off-by: Vlad Zolotarov Signed-off-by: Eilon Greenstein Signed-off-by: David S.
