Hi Harish,
The qede usage can be problematic, because of how QEDE_TX_OFFLOAD_MASK set:
#define QEDE_TX_OFFLOAD_MASK (QEDE_TX_CSUM_OFFLOAD_MASK | \
PKT_TX_VLAN_PKT | \
PKT_TX_TUNNEL_VXLAN | \
PKT_TX_TUNNEL_GENEVE | \
PKT_TX_TUNNEL_MPLSINUDP | \
PKT_TX_TUNNEL_GRE)
I am not sure if OFFLOAD_NOTSUP_MASK works fine with multi-bit values, I think
you should set `PKT_TX_TUNNEL_MASK` here.
But please double check in case I am missing something.
