Yan Burman d4676eac0d net: ethtool: Add destination MAC address to flow steering API
Add ability to specify destination MAC address for L3/L4 flow spec
in order to be able to specify action for different VM's under vSwitch
configuration. This change is transparent to older userspace.

Cong Wang cfd5675435 bridge: add support of adding and deleting mdb entries
This patch implents adding/deleting mdb entries via netlink.
Currently all entries are temp, we probably need a flag to distinguish
permanent entries too.

Eric Dumazet 1abbe1394a pkt_sched: avoid requeues if possible
With BQL being deployed, we can more likely have following behavior :

We dequeue a packet from qdisc in dequeue_skb(), then we realize target
tx queue is in XOFF state in sch_direct_xmit(), and we have to hold the
skb into gso_skb for later.

This shows in stats (tc -s qdisc dev eth0) as requeues.

Problem of these requeues is that high priority packets can not be
dequeued as long as this (possibly low prio and big TSO packet) is not
removed from gso_skb.

At 1Gbps speed, a full size TSO packet is 500 us of extra latency.

In some cases, we know that all packets dequeued from a qdisc are
for a particular and known txq :

- If device is non multi queue
- For all MQ/MQPRIO slave qdiscs

This patch introduces a new qdisc flag, TCQ_F_ONETXQUEUE to mark
this capability, so that dequeue_skb() is allowed to dequeue a packet
only if the associated txq is not stopped.

This indeed reduce latencies for high prio packets (or improve fairness
with sfq/fq_codel), and almost remove qdisc 'requeues'.

David Woodhouse cae49ede00 solos-pci: fix double-free of TX skb in DMA mode
We weren't clearing card->tx_skb[port] when processing the TX done interrupt.
If there wasn't another skb ready to transmit immediately, this led to a
double-free because we'd free it *again* next time we did have a packet to
send.

Rasesh Mody 478ab8c93a bna: Firmware update
Change Details:
 -      Added Stats clear counter to the bfi_enet_stats_mac structure and
        ethtool stats
 -      Modified the firmware naming convention to contain the firmware image
        version (3.1.0.0). The new convention is
        <firmware-image>-<firmware-version>.bin The change will enforce loading
        only compatible firmware with this driver and also avoid over-writing
        the old firmware image in-order to load new version driver as the
        firmware names used to be the same.

Rasesh Mody 215a64a25c bna: Add RX State
Change Details:
 -      BNA state machine for Rx in start_wait state moves it to stop_wait on
        receipt of RX_E_STOP. In Rx stop_wait state, on receipt of
                RX_E_STARTED event does enet stop
                RX_E_STOPPED event does rx_cleanup_cbfn
        rx_cleanup_cbfn in this case is called without post_cbfn. post_cbfn
        happens only after RX_E_STARTED event is received in start_wait. Without
        doing post_cbfn, NAPI remains disabled and in cleanup we try to disable
        again causing endless wait. ifconfig process and other workers can thus
        get stuck.
 -      Introducing start_stop_wait state for Rx. This state handles the case of
        if post_cbfn is not done simply do stop without the cleanup.

Gabor Juhos 36b07d15a6 ath9k: check pdata variable before dereferencing it
Due to my recent commit (ath9k: allow to load EEPROM
content via firmware API) smatch complains about that
the 'pdata' variable in 'ath9k_hw_init' can be NULL
and it is dereferenced before checking that. That is
absolutely correct.

Check the 'pdata' variable before using it to avoid
a NULL pointer dereference.

Cong Wang 2ce297fc24 bridge: fix seq check in br_mdb_dump()
In case of rehashing, introduce a global variable 'br_mdb_rehash_seq'
which gets increased every time when rehashing, and assign
net->dev_base_seq + br_mdb_rehash_seq to cb->seq.

In theory cb->seq could be wrapped to zero, but this is not
easy to fix, as net->dev_base_seq is not visible inside
br_mdb_rehash(). In practice, this is rare.
