[PATCH v3] USB: Extend usb_device_speed with new value USB_SPEED_SUPER_PLUS_BY2
From: Dingyan Li
Date: Fri Sep 01 2023 - 12:09:12 EST
Currently there are there major generations when speaking of
USB_SPEED_SUPER_PLUS devices. However, they actually stands
for different physical speeds. GEN_2x2 means 20Gbps, while
the others mean 10Gbps. So in order to confirm 20Gbps, both
speed and generation need ti be checked. This causes a trouble
for ioctl USBDEVFS_GET_SPEED since it can only return speed
value to userspace.
In order not to add a new ioctl to get ssp generation, extending
usb_device_speed is a good option. The side effect is that
USB_SPEED_SUPER_PLUS has been used in lots of places and
it also takes some effort to go through all of them and check
whether the new speed should be used too.
Besides, as suggested by Alen, ssp_rate is not a proper name,
change it to ssp_gen. And change all functions/struct fileds
ended with ssp_rate to ssp_gen. And there is also some code
refactor to reduce duplicate definition of strings and increase
the utilization of commonly defined utilities.
