Subject: Question about TPA/HDS feature of bnxt_en

Hi,
I'm currently testing the device memory TCP feature with the bnxt_en
driver because Broadcom NICs support TPA/HDS, which is a mandatory
feature for the devmem TCP.
But it doesn't work for short-sized packets(under 300?)
So, the devmem TCP stops or errors out if it receives non-header-splitted skb.

I hope the bnxt_en driver or firmware has options that force TPA to
work for short-sized packets.
So, Can I get any condition information on TPA?

Thanks a lot!
