This series of patches add support to offload flows to HASH region available on Chelsio T6 NICs. HASH region can only offload exact match (maskless) flows and hence the masks must be all set for all match items. Patch 1 queries firmware for HASH filter support. Patch 2 updates cxgbe_flow to decide whether to place flows in LE-TCAM or HASH region based on supported hardware configuration and masks of match items. Patch 3 adds Compressed Local IP (CLIP) region support for offloading IPv6 flows in HASH region. Also updates LE-TCAM region to use CLIP for offloading IPv6 flows on Chelsio T6 NICs. Patch 4 adds support for offloading flows to HASH region. Patch 5 adds support for deleting flows in HASH region. Patch 6 adds support to query hit and byte counters for offloaded flows in HASH region. Patch 7 adds support to flush filters in HASH region. Patch 8 adds support to match flows based on physical ingress port. Patch 9 adds support to redirect packets matching flows to specified physical egress port without sending them to host.

Hi Shagun, Rahul, Can you please update driver documentation [1] and release notes [2] for new added features, HASH(?) region offload support, CLIP region support etc... [1]: doc/guides/nics/cxgbe.rst [2]: doc/guides/rel_notes/release_18_08.rst Thanks, ferruh > > Patch 1 queries firmware for HASH filter support. > > Patch 2 updates cxgbe_flow to decide whether to place flows in LE-TCAM > or HASH region based on supported hardware configuration and masks of > match items. > > Patch 3 adds Compressed Local IP (CLIP) region support for offloading > IPv6 flows in HASH region.
