[Bug 2141234] [NEW] RTL8153 powersave quirk no longer works as expected

Public bug reported:

RTL8153 has some stupid default powersave settings that prevent a link
by default.

I was required to add

usbcore.quirks=0bda:8153:k

to my kernel commandline to revert back to the behavior seen since 6.8
in 24.04, through 6.17 in the latest version I had upgraded to before
switching to amd64v3 variant 26.04 on February 6th 2026.

Not sure where the quirk went, but the device won't function normally
without the kernel commandline.
