Re: [PATCH v1] USBNET: fix handling padding packet

Commit 638c5115a7949(USBNET: support DMA SG) introduces DMA SG
if the usb host controller is capable of building packet from
discontinuous buffers, but missed handling padding packet when
building DMA SG.

This patch attachs the pre-allocated padding packet at the
end of the sg list, so padding packet can be sent to device
if drivers require that.

Applied, thanks.

I still think the suggestion to disable scatter gather for
devices with the padding issue was the most sane approach
to solve this.

I guess people like supporting complicated crap and excess
code for things that pretty much do not exist, or at best
are not prominent enough to cater for at all.
