The following commit causes the pgv->buffer may point to the memory returned by vmalloc(). And we can't use virt_to_page() for the vmalloc address. This patch introduces a new inline function pgv_to_page(), which calls vmalloc_to_page() for the vmalloc address, and virt_to_page() for the __get_free_pages address. We used to increase page pointer to get the next page at the next page address, after Neil's patch, it is wrong, as the physical address may be not continuous. This patch also fixes this issue. commit 0e3125c7 Author: Neil Horman <nhorman@tuxdriver.com> Date: Tue Nov 16 10:26:47 2010 -0800 packet: Enhance AF_PACKET implementation to not require high order contiguous memory allocation (v4) Signed-off-by:Changli Gao <xiaosuo@gmail.com> Signed-off-by:

commits 9f0f7272 (ipv4: AF_INET link address family) and cf7afbfe (rtnl: make link af-specific updates atomic) used incorrect __in_dev_get_rcu() in RTNL protected contexts, triggering PROVE_RCU warnings. Switch to __in_dev_get_rtnl(), wich is more appropriate, since we hold RTNL. Based on a report and initial patch from Amerigo Wang. Reported-by:

If caller holds RTNL, we dont need a memory barrier (smp_read_barrier_depends) included in rcu_dereference(). Just use rtnl_dereference() to properly document the assertions. Signed-off-by:

Add SKF_AD_RXHASH and SKF_AD_CPU to filter ancillary mechanism, to be able to build advanced filters. This can help spreading packets on several sockets with a fast selection, after RPS dispatch to N cpus for example, or to catch a percentage of flows in one queue. tcpdump -s 500 "cpu = 1" : [0] ld CPU [1] jeq #1 jt 2 jf 3 [2] ret #500 [3] ret #0 # take 12.5 % of flows (average) tcpdump -s 1000 "rxhash & 7 = 2" : [0] ld RXHASH [1] and #7 [2] jeq #2 jt 3 jf 4 [3] ret #1000 [4] ret #0 Signed-off-by:

Remove ehea_error, ehea_info and ehea_debug macros. Use pr_fmt, pr_<level>, netdev_<level> and netif_<level> as appropriate. Fix messages to use trailing "\n", some messages had an extra one as the old ehea_<level> macros added a trailing "\n". Coalesced long format strings. Uncompiled/untested. Signed-off-by:

NETIF_F_HW_CSUM is a superset of NETIF_F_IP_CSUM+NETIF_F_IPV6_CSUM, but some drivers miss the difference. Fix this and also fix UFO dependency on checksumming offload as it makes the same mistake in assumptions. Signed-off-by:

The patch provides USB CDC NCM host driver support in the Linux Kernel. Changes: drivers/net/usb/cdc_ncm.c: - initial submission of the CDC NCM host driver; - verified on Intel 32/64 bit, Intel Atom, ST-Ericsson U8500 (ARM) - throughput measured over 100 Mbits duplex; - driver supports 16-bit NTB format only, but it is more than enough for transfers up to 64K; - driver can handle up to 32 datagrams in received NTB; - timer is used to collect several packets in Tx direction drivers/net/usb/Kconfig: - a new entry to compile CDC NCM host driver drivers/net/usb/Makefile: - a new entry to compile CDC NCM host driver Signed-off-by:

Changes: include/linux/usb/usbnet.h: - a new flag to indicate driver's capability to accumulate IP packets in Tx direction and extract several packets from single skb in Rx direction. drivers/net/usb/usbnet.c: - the procedure of counting packets in usbnet was updated due to the accumulating of IP packets in the driver - no short packets are sent if indicated by the flag in driver_info structure Signed-off-by:

The hardware defaults to fairly aggressive EEE thresholds. While there appear to be no ill effects, this patch relaxes them, just as a precaution. Signed-off-by:

The first hunk of this patch makes sure that the driver checks for the appropriate preconditions before checking if EEE negotiation succeeded. More specifically the link needs to be full duplex for EEE to be enabled. The second and third hunks of this patch fix a bug where the eee advertisement register would be programmed with extra bits set. The fourth hunk of this patch makes sure the EEE capability flag is not set for 5718 A0 devices and that the device is not a serdes device. None of these modifications are strictly necessary. The driver / hardware still does the right thing. They are submitted primarily for correctness. Signed-off-by:

The mcfw *never* sends CMDDONE when rebooting. Changing this so that it always sends CMDDONE *before* REBOOT is easy on Siena, but it's not obvious that we could guarantee to be able to implement this on future hardware. Given this, I'm less convinced that the protocol should be changed. To reiterate the failure mode: The driver sees this: issue command receive REBOOT event Was that reboot event sent before the command was issued, or in response to the command? If the former then there will be a subsequent CMDDONE event, if the latter, then there will be no CMDDONE event. Options to resolve this are: 1. REBOOT always completes an outstanding mcdi request, and we set the credits count to ignore a subsequent CMDDONE event with mismatching seqno. 2. REBOOT never completes an outstanding mcdi request. If there is no CMDDONE event then we rely on the mcdi timeout code to complete the outstanding request, incurring a 10s delay. I'd argue that (2) is tidier, but that incurring a 10s delay is a little needless. Let's go with (1). Signed-off-by: -
