From: Niklas Söderlund Date: Mon, 4 Mar 2024 11:08:56 +0000 (+0100) Subject: ravb: Use the max frame size from hardware info for RZ/G2L X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=496863388136bcba95298ab7dacaf55489af2b02;p=linux.git ravb: Use the max frame size from hardware info for RZ/G2L Remove the define describing the RZ/G2L maximum frame size and only use the information in the hardware information struct. This will make it easier to merge the R-Car and RZ/G2L code paths. There is no functional change as both the define and the maximum frame length in the hardware information is set to 8K.
