Netmap, 4 seconds is not enough. #160

Closed SiGe closed 9 years ago

SiGe commented 9 years ago

Hello,

We are running tcpreplay with netmap. It seems like that sometimes waiting for 4 seconds is not enough. In our case I had to increase this wait to 10 seconds before the NIC was ready to accept packets. Maybe you could accept an option from the user, similar to pkt-gen's -w option, that specifies this wait time? If you would like I can submit a patch for this.

We are using a 48 core AMD machine, with X520 NICs (10Gbps) from Intel.

Sounds like a good idea. Note that in 4.0.6 we plan to introduce a Quick TX module which is simpler to use than netmap. It installs as a module, and doesn't require source code on the local machine.
