VMA WARNING: qpm[0x7f506542f100]:99:configure() Allocating only 16336 Rx QP work requests while user requested VMA_RX_WRE=160000 for QP on <0x15777b0, 2>

on a ConnectX3 when I set VMA_RX_WRE=160000 (ie: 160,000). The default seems to be 16,000, and it seems to max out at 16,336.

How do I increase the number of Rx QP work requests?

I’m pretty sure that 16336 is the maximum number you can use.VMA tunes this according to the HCA capabilities and just warns the user of a change exceeding the HCA’s limit…
