 Module Name:	src
 Committed By:	aymeric

 Modified Files:
 	src/sys/dev/ic: dwc_gmac.c dwc_gmac_reg.h dwc_gmac_var.h

 Log Message:
 Revert the recent support for enhanced descriptors until a viable solution is
 found.

 It broke at least Cubietruck, Orange Pi One, and maybe Rock64 ethernets in
 different ways. Unfortunately it works on my Olinuxino Micro and Lime 2 so I
 can't reproduce the bugs for now.

 Should fix PR#53637

 Hi,

 thank you for reporting the bug. I reverted my patch; just for the

 now?

Aymeric, want me to commit my version or are you dealing with it?

 I'm fine with you committing it, you clearly fixed the endianness
 issue. Are you positive your patch also fixes the Rock64 case? If that's
 the case, then go for it.

 (On my side I'm working on making the nanosoc run in big-endian mode to
 test further the enhanced descriptors case.)

 Best regards,
  Aymeric

 Not positive, but I hope the core version check will deal with that.

 So I talked to the OP off list and it seems (IIUC) this PR is not about
 the gmac descriptor change, but unrelated emac failure.

 The issue only shows up when booting with no ethernet connected:

 [ 1.000040] emac0 at simplebus1: EMAC
 [ 1.000040] emac0: Ethernet address 02:81:52:c9:c3:81
 [ 1.000040] emac0: autoconfiguration error: soft reset timed out

 while it works fine when the ethernet is plugged in at boot time.

 Jared, would you happen to have a board with emac and can you reproduce
 this?

 My orangepi zeros arrived and I can reproduce the issue.

 Hi,

 is there any update on this bug? It had nothing to do with awge, so if
 anyone has data or wants to take ownership, that would be nice.

 ISTR jmcneill@ made a couple of commits related to the issue.

 Regards,
  Aymeric
