Well, it doesn't compile:
/local/kananye1/dpdk.org-ixgbevfix2-tst1/drivers/net/ixgbe/ixgbe_rxtx.c: In function âixgbe_rx_scan_hw_ringâ:
/local/kananye1/dpdk.org-ixgbevfix2-tst1/drivers/net/ixgbe/ixgbe_rxtx.c:1114:4: error: implicit declaration of function ârte_le_to_cpu16â [-Werror=implicit-function-declaration]
pkt_len = rte_le_to_cpu16(rxdp[j].wb.upper.length) -
^
/local/kananye1/dpdk.org-ixgbevfix2-tst1/drivers/net/ixgbe/ixgbe_rxtx.c:1114:4: error: nested extern declaration of ârte_le_to_cpu16â [-Werror=nested-externs]
Should be rte_le_to_cpu_16(), I believe.
And checkpatch.pl complains on it:
WARNING: line over 80 characters

Apart from that, looks harmless :)
