From: Michael Chan Date: Fri, 8 Jan 2016 00:56:57 +0000 (-0500) Subject: bnxt_en: Zero pad firmware messages to 128 bytes. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d79979a103f7820d3107cdc04096e87b37f90008;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git bnxt_en: Zero pad firmware messages to 128 bytes. For future compatibility, zero pad all messages that the driver sends to the firmware to 128 bytes. If these messages are extended in the future with new byte enables, zero padding these messages now will guarantee future compatibility. Signed-off-by: Michael Chan Signed-off-by: David S.
