Subject: [dpdk-dev] [PATCH] ixgbe: fix ixgbevf RX/TX function assignment
Date: Sun, 28 Feb 2016 23:07:30 +0800 [thread overview]
Message-ID: <1456672050-21115-1-git-send-email-zhe.tao@intel.com> (raw)
For the secondary process of DPDK to initialize ixgbevf, it will always
use the simple RX function or LRO RX function, and this behavior is not
the same RX/TX function selection logic as it is for the primary process,
so use the ixgbe_set_tx_function and ixgbe_set_rx_function to select the
RX/TX function when secondary process call the init function for eth dev.
