X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=fe5f098055ed7f701bfb16f8f87378cf67de9a0e;p=openwrt%2Fstaging%2Fblogic.git

qlge: reset the chip before freeing the buffers

Qlge is freeing the buffers before stopping the card DMA, and
this can cause some severe error, as a EEH event on PPC.

This patch just stop the card and then free the resources.
