Subject: net: thunderx: Fix TCP/UDP checksum offload for IPv6 pkts
|
||
|
|
|
||
|
|
Don't offload IP header checksum to NIC.
|
||
|
|
|
||
|
|
This fixes a previous patch which enabled checksum offloading
|
||
|
|
for both IPv4 and IPv6 packets. So L3 checksum offload was
|
||
|
|
getting enabled for IPv6 pkts. And HW is dropping these pkts
|
||
|
|
as it assumes the pkt is IPv4 when IP csum offload is set
|
||
|
|
in the SQ descriptor.
|
||
|
|
|
||
|
|
Fixes: 3a9024f52c2e ("net: thunderx: Enable TSO and checksum offloads for ipv6")
