2012-07-10net: calxedaxgmac: fix hang on rx refillRob Herring1-15/+12
Fix intermittent hangs in xgmac_rx_refill. If a ring buffer entry already had an skb allocated, then xgmac_rx_refill would get stuck in a loop. This can happen on a rx error when we just leave the skb allocated to the entry.

On 64 bit arches having efficient unaligned accesses (eg x86_64) we can use long words to reduce number of instructions for free.

2012-07-10ipv4: Calling ->cow_metrics() now is a bug.David S. Miller1-28/+2
Nothing every writes to ipv4 metrics any longer. PMTU is stored in rt->rt_pmtu. Dynamic TCP metrics are stored in a special TCP metrics cache, completely outside of the routes. Therefore ->cow_metrics() can simply nothing more than a WARN_ON trigger so we can catch anyone who tries to add new writes to ipv4 route metrics. Signed-off-by: David S. Miller <davem@davemloft.net>

2012-07-10tcp: Maintain dynamic metrics in local cache.David S. Miller4-93/+468
Maintain a local hash table of TCP dynamic metrics blobs. Computed TCP metrics are no longer maintained in the route metrics. The table uses RCU and an extremely simple hash so that it has low latency and low overhead. A simple hash is legitimate because we only make metrics blobs for fully established connections. Some tweaking of the default hash table sizes, metric timeouts, and the hash chain length limit certainly could use some tweaking. But the basic design seems sound.

2012-07-09net/fsl_pq_mdio: use spin_event_timeout() to poll the indicator registerTimur Tabi1-10/+19
Macro spin_event_timeout() was designed for simple polling of hardware registers with a timeout, so use it when we poll the MIIMIND register. This allows us to return an error code instead of polling indefinitely. Note that PHY_INIT_TIMEOUT is a count of loop iterations, so we can't use it for spin_event_timeout(), which asks for microseconds.
