2009-01-15b44: GFP_DMA skb should not escape from driverEric Dumazet
b44 chip has some hardware limitations, that need GFP_DMA bounce buffers in some situations. In order to not deplete DMA zone, we should keep allocated GFP_DMA skb only for driver use. At rx time, we copy such skb to newly allocated skb, reusing existing copybreak infrastructure. On machines with low amount of memory, all skb meet the hardware limitation, so no copy is needed. We detect this situation using a new device flag, set to one if one GFP_DMA skb was ever allocated by b44_alloc_rx_skb(). Previously allocated skb, even outside from DMA zone will then be recycled, to have minimal impact on DMA zone use.

2009-01-15korina: do not use IRQF_SHARED with IRQF_DISABLEDPhil Sutter
As the kernel warning states: "IRQF_DISABLED is not guaranteed on shared IRQs". Since these IRQs' values are hardcoded and my test system doesn't show any shared use of IRQs at all, rather make them non-shared than non-disabled.

2009-01-15korina: do not stop queue herePhil Sutter
Apparently this doesn't make sense. Otherwise the queue gets disabled as soon as it's getting empty and can only be resurrected by a driver restart. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Acked-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-15korina: fix handling tx_chain_tailPhil Sutter
Originally this must have been a rewrite error when introducing 'chain_index'. But the original driver did not use the previous chain item everywhere: when altering the address tx_chain_tail points to, it should move forward, not backwards. Also this is not an "index" but rather the penultimate element in the chain, so rename it accordingly.

2009-01-15korina: do tx at the right positionPhil Sutter
Triggering TX before the write to the DMA status mask register leads to transferring packets with maximum payload no matter what the actual packet size is. While here, also trigger RX scheduling after writing the DMA status mask register, like it was in the original driver before it was sent upstream.

2009-01-15korina: do schedule napi after testing for itPhil Sutter
The called netif_rx_schedule() does all the work for us: - it checks the return value of netif_rx_schedule_prep() and - if everything is ok calls __netif_rx_schedule(). Before this change, the driver received absolutely nothing. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Acked-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-15korina: rework korina_rx() for use with napiPhil Sutter
This function needs an early exit condition to function properly, or else caller assumes napi workload wasn't enough to handle all received packets and korina_rx is called again (and again and again and ...).

2009-01-15korina: reset resource buffer size to 1536Phil Sutter
The new value is the one used in the external patch before and allows at least a standard MTU of 1500 to be handled correctly. Impact of this change gets visible when bigger packets are to be received, issuing: | ping -s 492 <IP> and bigger payload sized led to 100% packet loss.

2009-01-15korina: fix usage of driver_dataPhil Sutter
Using platform_set_drvdata() here makes no sense, since the driver_data field has already been filled with valuable data (i.e. the MAC address). Also having driver_data point to the net_device is rather pointless since struct korina_device contains an apropriate field for it.

2009-01-15bnx2x: Using singlethread work queueEilon Greenstein
Since slow-path events, including link update, are handled in work-queue, a race condition was introduced in the self-test that sometimes caused the link status to fail: the self-test was running under RTNL lock, and if the link-watch was scheduled it stoped the shared work-queue (waiting for the RTNL lock) and so the link update event was not handled until the self-test ended (releasing the RTNL lock) with failure (since the link status was not updated) Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

2009-01-14net: Add init_dummy_netdev() and fix EMAC driver using itBenjamin Herrenschmidt
This adds an init_dummy_netdev() function that gets a network device structure (allocation and lifetime entirely under caller's control) and initialize the minimum amount of fields so it can be used to schedule NAPI polls without registering a full blown interface. This is to be used by drivers that need to tie several hardware interfaces to a single NAPI poll scheduler due to HW limitations. It also updates the ibm_newemac driver to use that, this fixing the oops on 2.6.29 due to passing NULL as "dev" to netif_napi_add() Symbol is exported GPL only a I don't think we want binary drivers doing that sort of acrobatics (if we want them at all).
