Subject: [PATCH 6/7] dsa: marvell: Correct value of max_frame_size variable after validation
Date: Thu,  9 Mar 2023 13:54:20 +0100	[thread overview]
Message-ID: <20230309125421.3900962-7-lukma@denx.de> (raw)
In-Reply-To: <20230309125421.3900962-1-lukma@denx.de>

Running of the mv88e6xxx_validate_frame_size() function provided following
results:

[    1.585565] BUG: Marvell 88E6020 has differing max_frame_size: 1632 != 2048
[    1.592540] BUG: Marvell 88E6071 has differing max_frame_size: 1632 != 2048
		^------ Correct -> mv88e6250 family max frame size = 2048B

[    1.599507] BUG: Marvell 88E6085 has differing max_frame_size: 1632 != 1522
[    1.606476] BUG: Marvell 88E6165 has differing max_frame_size: 1522 != 1632
[    1.613445] BUG: Marvell 88E6190X has differing max_frame_size: 10240 != 1522
[    1.620590] BUG: Marvell 88E6191X has differing max_frame_size: 10240 != 1522
[    1.627730] BUG: Marvell 88E6193X has differing max_frame_size: 10240 != 1522
		^------ Needs to be fixed!!!

[    1.634871] BUG: Marvell 88E6220 has differing max_frame_size: 1632 != 2048
[    1.641842] BUG: Marvell 88E6250 has differing max_frame_size: 1632 != 2048
		^------ Correct -> mv88e6250 family max frame size = 2048B

This commit removes the validation function and provides correct values
for the max frame size field.
