2010-07-07net: fix 64 bit counters on 32 bit archesEric Dumazet
There is a small possibility that a reader gets incorrect values on 32 bit arches. SNMP applications could catch incorrect counters when a 32bit high part is changed by another stats consumer/provider. One way to solve this is to add a rtnl_link_stats64 param to all ndo_get_stats64() methods, and also add such a parameter to dev_get_stats(). Rule is that we are not allowed to use dev->stats64 as a temporary storage for 64bit stats, but a caller provided area (usually on stack) Old drivers (only providing get_stats() method) need no changes.

2010-07-05isdn: avoid calling tty_ldisc_flush() in atomic contextTilman Schmidt
Remove the call to tty_ldisc_flush() from the RESULT_NO_CARRIER branch of isdn_tty_modem_result(), as already proposed in commit 00409bb045887ec5e7b9e351bc080c38ab6bfd33. This avoids a "sleeping function called from invalid context" BUG when the hardware driver calls the statcallb() callback with command==ISDN_STAT_DHUP in atomic context, which in turn calls isdn_tty_modem_result(RESULT_NO_CARRIER, ~), and from there, tty_ldisc_flush() which may sleep.

2010-07-05igb: drop support for UDP hashing w/ RSSAlexander Duyck
This change removes UDP from the supported protocols for RSS hashing. The reason for removing this protocol is because IP fragmentation was causing a network flow to be broken into two streams, one for fragmented, and one for non-fragmented and this in turn was causing out-of-order issues.

2010-07-01igb: Use only a single Tx queue in SR-IOV modeGreg Rose
The 82576 expects the second rx queue in any pool to receive L2 switch loop back packets sent from the second tx queue in another pool. The 82576 VF driver does not enable the second rx queue so if the PF driver sends packets destined to a VF from its second tx queue then the VF driver will never see them. In SR-IOV mode limit the number of tx queues used by the PF driver to one. This patch fixes a bug reported in which the PF cannot communciate with the VF and should be considered for 2.6.34 stable.
