Re: kern/57830: Xennet devices don't work properly with other NetBSD10 clients

[Dean Anderson <dean.anderson71%yahoo.com@localhost>]

I tried the suggested fix on file (renamed to xennetback_xenbus in RC2) and rebuilt GENERIC.

No change in behavior.

However, this maybe should be a separate bug:

When you follow the instructions in man 7 module to rebuild modules, by setting OBJDIR and TOOLDIR environment vars, it fails, but I don’t have the complete source trees installed, just syssrc.  So I’m not sure if it shows work without the full set of sources… but I’d argue it should work with only syssrc installed.

Thanks,
