When NetworkManager is enabled, there are chances that interface up is called even before probe completes. This means we have not yet allocated the FW sge queues, hence rest of ingress queue allocation wont be proper. Fix this by calling setup_fw_sge_queues() before register_netdev().

Unlike the moder modern SYSTEMPORT hardware, we do not have a configurable TDMA timeout, which limits us to implement adaptive RX interrupt coalescing only. We have each of our RX rings implement a bcmgenet_net_dim structure which holds an interrupt counter, number of packets, bytes, and a container for a net_dim instance.

Andrew Lunn says: ==================== Fixes to allow mv88e6xxx module to be reloaded As reported by Uwe Kleine-König, the interrupt trigger is first configured by DT and then reconfigured to edge. This results in a failure on EPROBE_DEFER, or if the module is unloaded and reloaded. A second crash happens on module reload due to a missing call to the common IRQ free code when using polled interrupts. With these fixes in place, it becomes possible to load and unload the kernel modules a few times without it crashing. v2: Fix the ü in Künig a couple of times v3: But the ü should be an ö! ==================== Signed-off-by: NDavid S.

By calling request_threaded_irq() with the flag IRQF_TRIGGER_FALLING we override the trigger mode provided in device tree.

As defined in hyperv_net.h, the NVSP_STAT_SUCCESS is one not zero. Some functions returns 0 when it actually means NVSP_STAT_SUCCESS. This patch fixes them. In netvsc_receive(), it puts the last RNDIS packet's receive status for all packets in a vmxferpage which may contain multiple RNDIS packets. This patch puts NVSP_STAT_FAIL in the receive completion if one of the packets in a vmxferpage fails. Signed-off-by: NHaiyang Zhang <haiyangz@microsoft.com> Signed-off-by: NDavid S.

Yonghong Song says: ==================== net: permit skb_segment on head_frag frag_list skb One of our in-house projects, bpf-based NAT, hits a kernel BUG_ON at function skb_segment(), line 3667. The bpf program attaches to clsact ingress, calls bpf_skb_change_proto to change protocol from ipv4 to ipv6 or from ipv6 to ipv4, and then calls bpf_redirect to send the changed packet out. ... 3665 while (pos < offset + len) { 3666 if (i >= nfrags) { 3667 BUG_ON(skb_headlen(list_skb)); ... The triggering input skb has the following properties: list_skb = skb->frag_list; skb->nfrags != NULL && skb_headlen(list_skb) != 0 and skb_segment() is not able to handle a frag_list skb if its headlen (list_skb->len - list_skb->data_len) is not 0. Patch #1 provides a simple solution to avoid BUG_ON. If list_skb->head_frag is true, its page-backed frag will be processed before the list_skb->frags. Patch #2 provides a test case in test_bpf module which constructs a skb and calls skb_segment() directly. The test case is able to trigger the BUG_ON without Patch #1. The patch has been tested in the following setup: ipv6_host <-> nat_server <-> ipv4_host where nat_server has a bpf program doing ipv4<->ipv6 translation and forwarding through clsact hook bpf_skb_change_proto. Changelog: v5 -> v6: . Added back missed BUG_ON(!nfrags) for zero skb_headlen(skb) case, plus a couple of cosmetic changes, from Alexander. v4 -> v5: . Replace local variable head_frag with a static inline function skb_head_frag_to_page_desc which gets the head_frag on-demand. This makes code more readable and also does not increase the stack size, from Alexander. . Remove the "if(nfrags)" guard for skb_orphan_frags and skb_zerocopy_clone as I found that they can handle zero-frag skb (with non-zero skb_headlen(skb)) properly. . Properly release segment list from skb_segment() in the test, from Eric. v3 -> v4: . Remove dynamic memory allocation and use rewinding for both index and frag to remove one branch in fast path, from Alexander. . Fix a bunch of issues in test_bpf skb_segment() test, including proper way to allocate skb, proper function argument for skb_add_rx_frag and not freeint skb, etc., from Eric. v2 -> v3: . Use starting frag index -1 (instead of 0) to special process head_frag before other frags in the skb, from Alexander Duyck. v1 -> v2: . Removed never-hit BUG_ON, spotted by Linyu Yuan. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2018-03-23 This series contains updates to ixgbe and ixgbevf only. Paul adds status register reads to reduce a potential race condition where registers can read 0xFFFFFFFF during a PCI reset, which in turn causes the driver to remove the adapter. Then fixes an assignment operation with an "OR" operation. Shannon Nelson provides several IPsec offload cleanups to ixgbe, as well as a patch to enable TSO with IPsec offload. Tony provides the much anticipated XDP support for ixgbevf. Currently, pass, drop and XDP_TX actions are supported, as well as meta data and stats reporting.

The current page counting scheme assumes that the reference count cannot decrease until the received frame is sent to the upper layers of the networking stack. This assumption does not hold for the XDP_REDIRECT action, since a page (pointed out by xdp_buff) can have its reference count decreased via the xdp_do_redirect call. To work around that, we now start off by a large page count and then don't allow a refcount less than two.
