[dpdk-dev] how to control receive timer for the wthresh?

Hi all,

Is there, on dpdk 1.6, an API for controlling the receive timer (EITR)
expiration of the wthresh on the NICs?
when setting, for example, .wthresh to 4 and transmitting 7 packets to the
application, then the last 3 packets remains in the on-chip-buffer for too
long and are written to the host memory only after few seconds, which is
not acceptable (in my case using 82575).

is there a way to config this?

Thanks
Sim
