The IRQ used by the Blackfin EMAC is internal to the peripheral and cannot be used to generate any other interrupt, so there is no point in marking it as IRQF_SHARED.

Somewhat luckily, I was looking into these parts with very fine comb because I've made somewhat similar changes on the same area (conflicts that arose weren't that lucky though). The loop was very much overengineered recently in commit 91521944 (tcp: Use SKB queue and list helpers instead of doing it by-hand), while it basically just wants to know if there are skbs after 'skb'. Also it got broken because skb1 = skb->next got translated into skb1 = skb1->next (though abstracted) improperly. Note that 'skb1' is pointing to previous sk_buff than skb or NULL if at head. Two things went wrong: - We'll kfree 'skb' on the first iteration instead of the skbuff following 'skb' (it would require required SACK reneging to recover I think). - The list head case where 'skb1' is NULL is checked too early and the loop won't execute whereas it previously did. Conclusion, mostly revert the recent changes which makes the cset very messy looking but using proper accessor in the previous-like version. The effective changes against the original can be viewed with: git-diff 91521944^ \ net/ipv4/tcp_input.c | sed -n -e '57,70 p' Signed-off-by: NIlpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: NDavid S.

[PATCH net-next] bonding: allow bond in mode balance-alb to work properly in bridge -try4.3 (updated) changes v4.2 -> v4.3 - memcpy the address always, not just in case it differs from master->dev_addr - compare_ether_addr_64bits() is not used so there is no direct need to make new header file (I think it would be good to have bond stuff in separate file anyway). changes v4.1 -> v4.2 - use skb->pkt_type == PACKET_HOST compare rather then comparing skb dest addr against skb->dev->dev_addr The problem is described in following bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=487763 Basically here's what's going on. In every mode, bonding interface uses the same mac address for all enslaved devices (except fail_over_mac). Only balance-alb will simultaneously use multiple MAC addresses across different slaves. When you put this kind of bond device into a bridge it will only add one of mac adresses into a hash list of mac addresses, say X. This mac address is marked as local. But this bonding interface also has mac address Y. Now then packet arrives with destination address Y, this address is not marked as local and the packed looks like it needs to be forwarded. This packet is then lost which is wrong. Notice that interfaces can be added and removed from bond while it is in bridge. *** When the multiple addresses for bridge port approach failed to solve this issue due to STP I started to think other way to solve this. I returned to previous solution but tweaked one. This patch solves the situation in the bonding without touching bridge code. For every incoming frame to bonding the destination address is compared to current address of the slave device from which tha packet came. If these two match destination address is replaced by mac address of the master. This address is known by bridge so it is delivered properly. Note that the comparsion is not made directly, it's used skb->pkt_type == PACKET_HOST instead. This is "set" previously in eth_type_trans(). I experimentally tried that this works as good as searching through the slave list (v4 of this patch).

When the i2400m is connected to a network, the host interface (USB) cannot be suspended. For that to happen, the device has to have negotiated with the basestation to put the link on IDLE state. If the host tries to put the device in standby while it is connected but not idle, the device resets, as the driver should not do that. To avoid triggering that, when the USB susbsytem requires the driver to autosuspend the device, the driver checks if the device is not yet idle. If it is not, the request is requested (will be retried again later on after the autosuspend timeout). At some point the device will enter idle and the request will succeed (unless of course, there is network traffic, but at that point, there is no idle neither in the link or the host interface).

wimax connection manager / daemon has to know what is current state of the device. Previously it was only possible to get notification whet state has changed. Note: By mistake, the new generic netlink's number for WIMAX_GNL_OP_STATE_GET was declared inserting into the existing list of API calls, not appending; thus, it'd break existing API. Fixed by Inaky Perez-Gonzalez <inaky@linux.intel.com> by moving to the tail, where we add to the interface, not modify the interface.

Functions i2400m_report_tlv*() are only called from i2400m_report_hook(), called in a workqueue by i2400m_report_hook_work(). The scheduler checks for device readiness before scheduling. Added an extra check for readiness in i2400m_report_hook_work(), which makes all the checks down the line redundant. Obviously the device state could change in the middle, but error handling would take care of that. Signed-off-by: NInaky Perez-Gonzalez <inaky@linux.intel.com>

By running 'echo 1 > /sys/kernel/debug/wimax:wmxX/i2400m/trace_msg_from_user', the driver will echo to user space all the commands being sent to the device from user space, along with the responses. However, this only helps with the commands being sent from user space; with this patch, the trace hook is moved to i2400m_msg_to_dev(), which is the single access point for running commands to the device (both by user space and the kernel driver). This allows better debugging by having a complete stream of commands/acks and reports. Signed-off-by: NInaky Perez-Gonzalez <inaky@linux.intel.com>

When commands are sent from user space, trace both the command sent and the answer received over the "echo" pipe instead of over the "trace" pipe when command tracing is enabled. As well, when the device sends a reports/indications, send it over the "echo" pipe. The "trace" pipe is used by the device to send firmware traces; gets confusing. Another named pipe makes it easier to split debug information. Signed-off-by: NInaky Perez-Gonzalez <inaky@linux.intel.com>

The WiMAX i2400m driver needs to generate a fake source MAC address to fake an ethernet header (for destination, the card's MAC is used). This is the source of the packet, which is the basestation it came from. The basestation's mac address is not usable for this, as it uses its own namespace and it is not always available. Currently the fake source MAC address was being set to all zeros, which was causing trouble with bridging. Use random_ether_addr() to generate a proper one that creates no trouble.
