Uh... Sorry. Yes, it's merge artifact.

Generally, I prefer declaring such structures with ((packed)) regardless
of if it's really do something. Just to show that it should be packed.

Can you please verify that it works as well without the "packed", and
if it does (as expected) resubmit without it?

Thanks.

[U-Boot] [PATCH 2/3][v3] dnet: driver for Dave DNET ethernet controller

[Ilya Yanok]

Hello All,

Sorry guys, it looks like I posted the wrong version. Please discard
[v4] patch. I'll post [v5] version soon.

Regards, Ilya.

[U-Boot] [PATCH 2/3][v5] dnet: driver for Dave DNET ethernet controller

[Ilya Yanok]

Driver for Dave DNET ethernet controller (used on Dave/DENX
QongEVB-LITE board).
