Tested the new armhf kernel on RPi3B+; copied 40Mb and 600Mb files successfully with no issues. Compared performance of the 40Mb copy+sync to the same machine running Disco (which has dwc_otg) and performance on eoan with the new kernel was marginally quicker (6.8-7.0s on eoan with dwc2 vs 8.2s-8.5s on disco with dwc_otg). I'd guess that that's down to kernel improvements generally between disco and eoan rather than anything to do with the driver, but at least it demonstrates there's no performance regression.

Looking good overall!
