Subject: [PATCH] staging: fsl_ppfe/eth: remove jumbo frame enable from gemac
|
|
init
|
|
|
|
MAC Receive Control Register was configured to allow jumbo frames.
|
|
This is removed as jumbo frames can be supported anytime by changing
|
|
mtu which will in turn modify MAX_FL field of MAC RCR.
|
|
Jumbo frames caused pfe to hang on LS1012A rev 1.0 Silicon due to
|
|
erratum A-010897.
