[v2,06/10] kni: increase length of timeout for KNI responses
Checks
Commit Message
Increase the timeout to receive a response for KNI events handled
through kni_net_process_request to 10 seconds.
Certain actions, such as calling rte_eth_dev_start() can take more
than 3 seconds to return, in addition to any additional time needed
for the DPDK application to call rte_kni_handle_request().
