Subject: [PATCH] net: Make USO depend on CSUM offload
|
|
|
|
UDP segmentation offload inherently depends on checksum offload. It should
|
|
not be possible to disable checksum offload while leaving USO enabled.
|
|
Enforce this dependency in code.
|
|
|
|
There is a single tx-udp-segmentation feature flag to indicate support for
|
|
both IPv4/6, hence the devices wishing to support USO must offer checksum
|
|
offload for both IP versions.
|
|
|
|
Fixes: 10154dbded6d ("udp: Allow GSO transmit from devices with no checksum offload")
