2011-11-18bnx2: switch to build_skb() infrastructureEric Dumazet
This is very similar to bnx2x conversion, but bnx2 only requires 16bytes alignement at start of the received frame to store its l2_fhdr, so goal was not to reduce skb truesize (in fact it should not change after this patch) Using build_skb() reduces cache line misses in the driver, since we use cache hot skb instead of cold ones. Number of in-flight sk_buff structures is lower, they are more likely recycled in SLUB caches while still hot.

2011-11-18sky2: enforce minimum ring sizestephen hemminger
The hardware has a restriction that the minimum ring size possible is 128. The number of elements used is controlled by tx_pending and the overall number of elements in the ring tx_ring_size, therefore it is okay to limit the number of elements in use to a small value (63) but still provide a bigger ring.

2011-11-17stmmac: remove spin_lock in stmmac_ioctl.Srinivas Kandagatla
This patch removes un-needed spin_lock in stmmac_ioctl while reading and writing mdio registers. While holding spin_lock the code must be atomic, which is not true in this case as both mdiobus_read and writes have mutex locks.

2011-11-17stmmac: parameters auto-tuning through HW cap regGiuseppe CAVALLARO
New GMAC devices (newer than the databook 3.50a) have the HW capability register that provides which features are actually supported by the hardware. On old devices many information have to be passed through the platform, for example: enhanced descriptor structure, TX COE etc. These are mandatory to properly configure the driver. This remains still valid because the driver has to support old Synopsys devices but now it's also able to override them using the values from the HW capability register if supported.

2011-11-17forcedeth: stats updated with a deferrable timerdavid decotigny
Mark stats timer as deferrable: punctuality in waking the stats timer callback doesn't matter much, as it is responsible only to avoid integer wraparound. We need at least 1 other timer to fire within 17s (fully loaded 1Gbps) to avoid wrap-arounds. Desired period is still 10s.

2011-11-17forcedeth: allow to silence "TX timeout" debug messagesSameer Nanda
This adds a new module parameter "debug_tx_timeout" to silence most debug messages in case of TX timeout. These messages don't provide a signal/noise ratio high enough for production systems and, with ~30kB logged each time, they tend to add to a cascade effect if the system is already under stress (memory pressure, disk, etc.). By default, the parameter is clear, meaning that only a single warning will be reported. Signed-off-by: David Decotigny <david.decotigny@google.com> Signed-off-by: David S.

2011-11-17forcedeth: fix stats on hardware without extended stats supportdavid decotigny
This change makes sure that tx_packets/rx_bytes ifconfig counters are updated even on NICs that don't provide hardware support for these stats: they are now updated in software. For the sake of consistency, we also now have tx_bytes updated in software (hardware counters include ethernet CRC, and software doesn't account for it). This reverts parts of: - "forcedeth: statistics optimization" (21828163b2) - "forcedeth: Improve stats counters" (0bdfea8ba8) - "forcedeth: remove unneeded stats updates" (4687f3f364) Tested: pktgen + loopback (http://patchwork.ozlabs.org/patch/124698/) reports identical tx_packets/rx_packets and tx_bytes/rx_bytes.
