| | | | | | | | | | | | | | | | | | The NOLINK state will poll the phy once a second to see if the link has come up.

It's safe to ignore the new skb in the ipvlan_xmit_* functions, because they call ipvlan_rcv_frame with local == true, so that dev_forward_skb is called and always takes ownership of the skb.

| * via-velocity: unconditionally drop frames with bad l2 lengthTimo Teräs2015-11-171-21/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default the driver allowed incorrect frames to be received. What is worse the code does not handle very short frames correctly. The FCS length is unconditionally subtracted, and the underflow can cause skb_put to be called with large number after implicit cast to unsigned. And indeed, an skb_over_panic() was observed with via-velocity. This removes the module parameter as it does not work in it's current state, and should be implemented via NETIF_F_RXALL if needed.

| * dl2k: Add support for IP1000A-based cardsOndrej Zary2015-11-163-6/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for IP1000A chips to dl2k driver. IP1000A chip looks like a TC9020 with integrated PHY. This allows IP1000A chips to work reliably because the ipg driver is buggy - it loses packets under load and then completely stops transmitting data. Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps: vendor=0x13f0 device=0x1023 (rev 0x41) subsystem vendor=0x1043 device=0x8180 MAC address registers access needed to be changed from 8-bit to 16-bit because 8-bit does not work on IP1000A. 8-bit access is not even allowed in the TC9020 datasheet (although it worked). 16-bit access works on both. Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably a rebranded TC9020): vendor=0x1186 device=0x4000 (rev 0x0c) subsystem vendor=0x1186 device=0x4000 Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: David S.

By introducing new HW capability self_lb_en_modifiable, which indicates the support to modify self_lb_en bit in modify_tir command. When this capability is set we can prevent TIRs from sending back loopback multicast traffic to their own RQs, by "refreshing TIRs" with modify_tir command, on every time new channels (SQs/RQs) are created at device open. This is needed since TIRs are static and only allocated once on driver load, and the loopback decision is under their responsibility. Fixes issues of the kind: "IPv6: eth2: IPv6 duplicate address fe80::e61d:2dff:fe5c:f2e9 detected!"

In particular, we have and unsigned long QSGMII_PHY_CDR_EN == BIT(0) == (1ul << 0) == 0x0000000000000001ul and a signed int 0xC << QSGMII_PHY_TX_DRV_AMP_OFFSET == 0xc0000000 which together gives a signed long value 0xffffffffc0000001l and when this is passed into a function that takes an unsigned int type, gcc warns about the signed overflow and the loss of the upper 32-bits that are all ones. This patch adds 'ul' type modifiers to the literal numbers passed in here, so now the expression remains an 'unsigned long' with the upper bits all zero, and that avoids the signed overflow and the warning.

It includes usb-gadget, target w/ drivers, netconsole and ocfs2 changes to realize the improved simplicity, that now renders the original include/target/configfs_macros.h CPP magic for fabric drivers and others, unnecessary and obsolete. And with common code in place, new configfs attributes can be added easier than ever before. Note, there are further improvements in-flight from other folks for v4.5 code in configfs land, plus number of target fixes for post -rc1 code" In the meantime, a new user of the now-removed old configfs API came in through the char/misc tree in commit 7bd1d4093c2f ("stm class: Introduce an abstraction for System Trace Module devices"). This merge resolution comes from Alexander Shishkin, who updated his stm class tracing abstraction to account for the removal of the old show_attribute and store_attribute methods in commit 517982229f78 ("configfs: remove old API") from this pull. As Alexander says about that patch: "There's no need to keep an extra wrapper structure per item and the awkward show_attribute/store_attribute item ops are no longer needed. This patch converts policy code to the new api, all the while making the code quite a bit smaller and easier on the eyes.

Without that some iommu implementations may not work. pci_dma_supported is removed entirely, but dma_supported stays for dma_ops implementations for now. This patch (of 15): This ensures the dma mask that is supported by the driver is recorded in the device structure.
