Subject: [net PATCH] octeontx2-pf: Dont allocate BPIDs for LBK interfaces
Date: Sun, 16 Jul 2023 15:07:41 +0530 [thread overview]
Message-ID: <20230716093741.28063-1-gakula@marvell.com> (raw)
Current driver enables backpressure for LBK interfaces.
But these interfaces do not support this feature.
Hence, this patch fixes the issue by skipping the
backpressure configuration for these interfaces.
Fixes: 75f36270990c ("octeontx2-pf: Support to enable/disable pause frames via ethtool").
