--------------------------------

[ Upstream commit 8fcd7c7b ]

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: 75f36270 ("octeontx2-pf: Support to enable/disable pause frames via ethtool").
