Subject: [PATCH net-next 2/8] qeth: fix handling of IPA return codes

From: Eugene Crosser <Eugene.Crosser@...ibm.com>

Function that executes IPA commands returns the result code from the
IPA response block. If non-negative, it needs to be transformed into
errno-compatible code before returning to the caller.
