[PATCH net] octeontx2-vf: set TC flower flag on MCAM entry allocation

From: Ratheesh Kannoth

Date: Wed Jul 15 2026 - 01:20:42 EST


From: Suman Ghosh <sumang@xxxxxxxxxxx>

When MCAM entries are allocated for a VF netdev via the devlink
mcam_count parameter, only OTX2_FLAG_NTUPLE_SUPPORT was set. That
enabled ethtool ntuple filters but not tc flower offload. Also set
OTX2_FLAG_TC_FLOWER_SUPPORT when entries are successfully allocated.

Fixes: 2da489432747 ("octeontx2-pf: devlink params support to set mcam entry count")
