I found recently that the arp_process function which handles all of our received arp frames, is using IPV4_DEVCONF_ALL macro to check the state of the arp_process flag. This seems wrong, as it implies that either none or all of the network interfaces accept gratuitous arps. This patch corrects that, allowing per-interface arp_accept configuration to deviate from the all setting. Note this also brings us into line with the way the arp_filter setting is handled during arp_process execution. Tested this myself on my home network, and confirmed it works as expected.

If host is going to autosuspend function with two interfaces and if IP packet has arrived in-between of two usbnet_suspend() callbacks, i.e usbnet_resume() is called in-between, tx data flow is stopped. When autosuspend timer expires and device is put to autosuspend again, tx queue is waked up and data can be sent again. This behavior might be repeated several times in a row. Tested on Intel/ARM.

Change the datatype of "ip_addr" to __be32 as 'ip' should be in big endian format. Adapter needs "ip address" in big endian format stored at lower 32bit of req.word[1]. netxen_config_ipaddr() now receives 'ip' in big endian format. To satisfy adapter's need, use memcpy() to copy byte by byte of 'ip' into lower 32bit of req.word[1]. Mac address and serial number of adapter need to be in little endian format. Change the data type of the related variables to __le32 / __le64 or cast it explicitly to __le32 / __le64 depending upon the requirement. Signed-off-by:

asix_rx_fixup() is complex, and does some unnecessary memory copies (at least on x86 where NET_IP_ALIGN is 0) Also, it tends to provide skbs with a big truesize (4096+256 with MTU=1500) to upper stack, so incoming trafic consume a lot of memory and I noticed early packet drops because we hit socket rcvbuf too fast. Switch to a different strategy, using copybreak so that we provide nice skbs to upper stack (including the NET_SKB_PAD to avoid future head reallocations in some paths) With this patch, I no longer see packets drops or tcp collapses on various tcp workload with a AX88772 adapter.

libertas provides a dump_survey implementation based on reading of a RSSI value. However, this RSSI value is calculated based on the last received beacon from the associated AP - it is not a good way of surveying a channel in general, and even causes an error if the card is not associated to a network. As this is not appropriate as a survey, remove it. This fixes an issue where something in userspace is repeatedly calling site-survey during boot, resulting in many repeated errors as the RSSI value cannot be read before associating. Signed-off-by:

Some debugfs write functions call kstrto* functions, which assume the string is null-terminated. Make it valid by changing ieee80211_if_write() to use static buffer instead of allocating one, and set the last char to NULL. (The write functions try to parse some integer/mac address, so 64 bytes buffer should be enough) Signed-off-by:

The current max throughput rate is known to be good as otherwise it wouldn't be the max throughput rate. Since rate sampling can introduce some overhead (by adding RTS for example or due to not aggregating the frame) don't sample the max throughput rate. Signed-off-by:

TX status fifo is limited to 16 elements. When we send more frames than that, we can easily loose status, what is not good for rate scaling algorithm. On my testing the change does not degrade performance, actually make is slightly better. Additionally with the patch I can see much less various rt2x00 warnings in dmesg. Signed-off-by:

Tx statuses of aggregated subframes contain packetid of first subframe in the AMPDU. We can not identify AMPDU subframes based on packedid, so simply assume that status match first pending frame in the queue. Thats mostly the same what 2800pci do. Signed-off-by:

Currently we read tx status register after each urb data transfer. As callback procedure also trigger reading, that causing we have many "threads" of reading status. To prevent that introduce TX_STATUS_READING flags, and check if we are already in process of sequential reading TX_STA_FIFO, before requesting new reads. Change timer to hrtimer, that make TX_STA_FIFO overruns less possible. Use 200 us for initial timeout, and then reschedule in 100 us period, this values probably have to be tuned. Make changes on txdone work. Schedule it from rt2800usb_tx_sta_fifo_read_completed() callback when first valid status show up. Check in callback if tx status timeout happens, and schedule work on that condition too. That make possible to remove tx status timeout from generic watchdog. I moved that to rt2800usb. Loop in txdone work, that should prevent situation when we queue work, which is already processed, and after finish work is not rescheduled again. Signed-off-by:

Patch change txdone code to make it similar like txdone in rt2800pci, process only one entry from queue matching tx status. Before we processed all pending entries from queue until PACKEDID match, that caused that we do not report tx statuses correctly. Signed-off-by:
