2009-03-21sfc: Implement adaptive IRQ moderationBen Hutchings
Calculate a score for each 1000 IRQs: - TX completions are worth 1 point - RX completions are worth 4 if merged using LRO or 2 otherwise Reduce moderation if the score is less than 10000, down to a minimum of 5 us. Increase moderation if the score is more than 20000, up to the specified maximum. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-03-21sfc: Work around unreliable legacy interrupt statusBen Hutchings
In rare cases, reading the legacy interrupt status register can acknowledge an event queue whose attention flag has not yet been set in the register. Until we service this event queue it will not generate any more interrupts. Therefore, as a secondary check, poll the next slot in each active event queue whose flag is not set.

2009-03-21igb: cleanup tx dma so map & unmap use matching callsAlexander Duyck
The igb driver was using map_single to map the skbs and then unmap_page to unmap them. This update changes that so instead uses skb_dma_map and skb_dma_unmap.

2009-03-21igb: allow tx of pre-formatted vlan tagged packetsArthur Jones
When the 82575 is fed 802.1q packets, it chokes with an error of the form: igb 0000:08:00.1 partial checksum but proto=81! As the logic there was not smart enough to look into the vlan header to pick out the encapsulated protocol. There are times when we'd like to send these packets out without having to configure a vlan on the interface. Here we check for the vlan tag and allow the packet to go out with the correct hardware checksum. Thanks to Kand Ly <kand@riverbed.com> for discovering the issue and the coming up with a solution.

2009-03-21powerpc 4xx EMAC driver: device name reported on timeout is not correctMikhail Zolotaryov
Hi, IBM EMAC driver performs device reset (drivers/net/ibm_newemac/core.c: emac_probe() -> emac_init_phy() -> emac_reset()) before registering appropriate net_device (emac_probe() -> register_netdev()), so net_device name contains raw format string during EMAC reset ("eth%d"). If the case of reset timeout, emac_report_timeout_error() function is called to report an error. The problem is this function uses net_device name to report device related, which is not correct, as a result in the kernel log buffer we see: eth%d: reset timeout The solution is to print device_node full_name instead. After applying the patch proposed, error string is like the following: /plb/opb/ethernet@ef600e00: reset timeout Signed-off-by: Mikhail Zolotaryov <lebon@lebon.org.ua> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: David S.

2009-03-20ixgbe: Fixup the watchdog interrupt scheduling on 82599Jesse Brandeburg
The watchdog will schedule an interrupt to help make sure queues are cleaned in the case when an interrupt is missed, most likely due to very high load. On 82599, there are extra interrupt registers to account for the larger number of MSI-X vectors (64 total for 82599 vs. 18 total for 82598). These must be taken into account when performing this operation in the watchdog.

2009-03-18smsc911x: reset last known duplex and carrier on openSteve Glendinning
smsc911x_phy_adjust_link is called periodically by the phy layer (as it's run in polling mode), and it only updates the hardware when it sees a change in duplex or carrier. This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet.

Tulip is currently doing request_irq before it has done its initialization.
