Subject: [net-next PATCH V2 0/4] Priority flow control support for RVU netdev
Date: Wed, 9 Feb 2022 12:45:15 +0530 [thread overview]
Message-ID: <20220209071519.10403-1-hkelam@marvell.com> (raw)
In network congestion, instead of pausing all traffic on link
PFC allows user to selectively pause traffic according to its
class. This series of patches add support of PFC for RVU netdev
drivers.
Patch1 adds support to disable pause frames by default as
with PFC user can enable either PFC or 802.3 pause frames.
Patch2&3 adds resource management support for flow control
and configures necessary registers for PFC.
Patch4 adds dcb ops registration for netdev drivers.
V2 changes:
Fix compilation error by exporting required symbols 'otx2_config_pause_frm'
Hariprasad Kelam (3):
octeontx2-af: Don't enable Pause frames by default
octeontx2-af: Flow control resource management
octeontx2-pf: PFC config support with DCBx
