src/patches/suse-2.6.27.25/patches.arch/s390-11-04-lcs_hard_sx_rc.patch

   1 From: Gerald Schaefer <geraldsc@de.ibm.com>
   2 Subject: lcs: invalid return codes from hard_start_xmit.
   3 References: bnc#484767,LTC#52201
   4
   5 Symptom: Messages about invalid return codes in /var/log/messages. The data
   6 transmission works ok.
   7 Problem: LCS hard_start_xmit returns non-standard Return Codes.
   8 Solution: Now lcs returns only either NETDEV_TX_OK or NETDEV_TX_BUSY.
