  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.  

Fixes: abf7275bbaa2918 (ixgbe: move to drivers/net/)

V2:add fixes line

That doesn't look to be the commit that actually introduced the bug.
