2013-12-10pkt_sched: give visibility to mq slave qdiscsEric Dumazet4-9/+18
Commit 6da7c8fcbcbd ("qdisc: allow setting default queuing discipline") added the ability to change default qdisc from pfifo_fast to say fq But as most modern ethernet devices are multiqueue, we cant really see all the statistics from "tc -s qdisc show", as the default root qdisc is mq. This patch adds the calls to qdisc_list_add() to mq and mqprio Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e only. Jacob provides a i40e patch to get 1588 work correctly by separating TSYNVALID and TSYNINDX fields in the receive descriptor. Jesse provides several i40e patches, first to correct the checking of the multi-bit state. The hash is reported correctly in the RSS field if and only if the filter status is 3. Other values of the filter status mean different things and we should not depend on a bitwise result. Then provides a patch to enable a couple of workarounds based on revision ID that allow the driver to work more fully on early hardware. Shannon provides several i40e patches as well. First sets the media type in the hardware structure based on the external connection type. Then provides a patch to only setup the rings that will be used. Lastly provides a fix where the TESTING state was still set when exiting the ethtool diagnostics. Kevin Scott provides one i40e patch to add a new flag to the i40e_add_veb() which allows the driver to request the hardware to filter on layer 2 parameters. Anjali provides four i40e patches, first refactors the reset code in order to re-size queues and vectors while the interface is still up. Then provides a patch to enable all PCTYPEs expect FCoE for RSS. Adds a message to notify the user of how many VFs are initialized on each port. Lastly adds a new variable to track the number of PF instances, this is a global counter on purpose so that each PF loaded has a unique ID. Catherine bumps the driver version. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

We also need to reset the existing setup, update the configuration and then rebuild again. This requires us to have the reset flow broken down into two parts.

2013-12-07net: introduce dev_consume_skb_any()Eric Dumazet2-24/+74

We need to separate the two causes to get better diagnostics given by dropwatch or "perf record -e skb:kfree_skb" This patch provides two new helpers, dev_consume_skb_any() and dev_consume_skb_irq() to be used for consumed skbs. __dev_kfree_skb_irq() is slightly optimized to remove one atomic_dec_and_test() in fast path, and use this_cpu_{r|w} accessors.
