H A D | mcs.h | 00efd99e Tue Dec 05 02:04:30 CST 2023 Nithin Dabilpuram <ndabilpuram@marvell.com> octeontx2-af: Adjust Tx credits when MCS external bypass is disabled
[ Upstream commit dca6fa8644b89f54345e55501b1419316ba5cb29 ]
When MCS external bypass is disabled, MCS returns additional 2 credits(32B) for every packet Tx'ed on LMAC. To account for these extra credits, NIX_AF_TX_LINKX_NORM_CREDIT.CC_MCS_CNT needs to be configured as otherwise NIX Tx credits would overflow and will never be returned to idle state credit count causing issues with credit control and MTU change.
This patch fixes the same by configuring CC_MCS_CNT at probe time for MCS enabled SoC's
