Re: [dpdk-users] Send and Receive packets to/from specific core

[Mahdi Moradmand Badie <mahdi.mbadie@gmail.com>]

My big challenge is having a tested code (run able with right
functionality), then run and change it in order to have my task.
I wanna use the share memory btw cores in order to write/read to/from and
knowing how do that :), all available code which I found are based on NIC
:( or maybe I am wrong!!!
Thanks in advance,
