From: Chengwen Feng <fengcheng...@huawei.com> Currently, there are four control variables (rx_simple_allowed, rx_vec_allowed, tx_simple_allowed and tx_vec_allowed) which are used to impact the selection of Rx/Tx burst function.
The purpose of the design is to provide a way to control the selection of Rx/Tx burst function by modifying it's values, but these variables have no entry to modify unless make intrusive modifications. Now we already support runtime config to select Rx/Tx function, these variables could be removed.
