* qeth: Exploit Connection IsolationEinar Lueck2009-11-166-12/+267
| | | | | | | | | | | Isolate data connection to a shared OSA card against other data connections to the same OSA card. Connectivity between isolated data connections sharing the same OSA card is therefore possible only through external network gear (e.g. a router).

* bonding: fix 802.3ad standards compliance errorJay Vosburgh2009-11-151-42/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | The language of 802.3ad 43.4.9 requires the "recordPDU" function to, in part, compare the Partner parameter values in a received LACPDU to the stored Actor values. If those match, then the Partner's synchronization state is set to true. The current 802.3ad implementation is performing these steps out of order; first, the synchronization check is done, then the paramters are checked to see if they match (the synch check being done against a match check of a prior LACPDU). This causes delays in establishing aggregators in some circumstances. This patch modifies the 802.3ad code to call __choose_matched, the function that does the "match" comparisions, as the first step of __record_pdu, instead of immediately afterwards. This new behavior is in compliance with the language of the standard. Some additional commentary relating to code vs. standard is also added. Reported by Martin Patterson <martin@gear6.com> who also supplied the logic of the fix and verified the patch. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.
