    "content": "This patch removes l3_l4_xsum_errors from rx errors.\n\nThe reason to remove it is that UDP packets have an optional checksum, and\nwhen not calculated the checksum field should be set to zero. When the\nchecksum is not calculated (zero-ed out), the hardware still counts a valid\nUDP packet as an l3_l4_xsum_error.\n\nThis hardware issue is documented in 82599 errata, titled:\n\"Integrity Error Reported for IPv4/UDP Packets with Zero Checksum\"\n\nThe solution is to remove l3_l4_xsum_errors from rx_errors, as discussed on\nhttp://thread.gmane.org/gmane.comp.networking.dpdk.devel/25590/\n\nFixes: f6bf669b9900 (\"ixgbe: account more Rx errors\")\n\nSuggested-by: Martin Weiser <martin.weiser@allegro-packets.com>\nSigned-off-by: Harry van Haaren <harry.van.haaren@intel.com>\n---\n\nv2: Add fixes line\n\n drivers/net/ixgbe/ixgbe_ethdev.c | 1 -\n 1 file changed, 1 deletion(-)",
