The current code configures the Physical Function (PF) root node at TL1 and the Virtual Function (VF) root node at TL2. This ensure at any given point of time PF traffic gets more priority. PF root node TL1 / \ TL2 TL2 VF root node / \ TL3 TL3 / \ TL4 TL4 / \ SMQ SMQ Due to a bug in the current code, the TL2 parent queue index on the VF interface is not being configured, leading to 'SMQ Flush' errors Fixes: 5e6808b4c68d ("octeontx2-pf: Add support for HTB offload") Signed-off-by: Hariprasad Kelam <hkelam@marvell.com> --- drivers/net/ethernet/marvell/octeontx2/nic/qos.c | 5 +++++ 1 file changed, 5 insertions(+)
