From 50b4a3c23646254c7345f3663ff1e0a6cbcd9abb Mon Sep 17 00:00:00 2001 From: Huy Nguyen Date: Fri, 2 Mar 2018 15:47:01 -0600 Subject: net/mlx5: PPTB and PBMC register firmware command support Add firmware command interface to read and write PPTB and PBMC registers. PPTB register enables mappings priority to a specific receive buffer. PBMC registers enables changing the receive buffer's configuration such as buffer size, xon/xoff thresholds, buffer's lossy property and buffer's shared property.
