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.
