If qeth issues an ipa command, but for some reasons the response never comes back, qeth reaches a timeout. Reset the irq_pending flag of the write channel in timeout handling code and trigger a recovery to avoid endless looping for the following ipa command.

This patch serializes device removal and other sysfs-triggered configurations by moving removal of sysfs-attributes to the beginning of the remove functions. And it serializes online/offline setting and discipline-switching (causing reestablishing of the net_device) by making use of a new discipline mutex.

Turning on memory debugging showed there could be page breaks in hardware headers. OSA does not allow this so we had to add code to bounce the header in case there is a page break. This patch also fixes a problem in case the skb->data part of a fragmented skb spreads multiple pages. Signed-off-by: NFrank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: NDavid S.

This patch adds a debug area for each qeth card. This debug area will replace various other debug areas that are global for all cards handled by the device driver. On crash dump analysis this makes life easier when trying to find out what's going on with an interface. Also, the forest of debug areas for this device driver is significantly cleared up.
