Subject: [PATCH AlmaLinux 10] gve: Enable reading max ring size from the device in DQO-QPL mode
|
|
|
|
The gVNIC device indicates a device option (MODIFY_RING) to the driver,
|
|
which presents a range of ring sizes from which the user is allowed to
|
|
select. But in DQO-QPL queue format, the driver ignores the "max" of
|
|
this range and instead allows the user to configure the ring size in the
|
|
range [min, default]. This was done because increasing the ring size
|
|
could result in the number of registered pages being higher than the max
|
|
allowed by the device.
|
|
|
|
In order to support large ring sizes, stop ignoring the "max" of the
|
|
range presented in the MODIFY_RING option.
