* | | qed: Add driver API for flashing the config attributes.Sudarsana Reddy Kalluru2019-08-151-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds driver interface for reading the config attributes from user provided buffer, and updates these values on nvm config flash partition. This is basically an expansion of our existing ethtool -f implementation. The management FW has exposed an additional method of configuring some of the nvram options, and this makes use of that. This implementation will come into use when newer FW files which contain configuration directives employing this API will be provided to ethtool -f.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | strncpy() does not ensure NULL-termination when the input string size equals to the destination buffer size 30. The output string is passed to qed_int_deassertion_aeu_bit() which calls DP_INFO() and relies NULL-termination. Use strlcpy instead. The other conditional branch above strncpy() needs no fix as snprintf() ensures NULL-termination. This issue is identified by a Coccinelle script.

| | | | | | | | | | | | | | | | | | | | | | | Most drivers do the same thing to set up the flow block callbacks, this patch adds a helper function to do this. This preparation patch reduces the number of changes to adapt the existing drivers to use the flow block callback API. This new helper function takes a flow block list per-driver, which is set to NULL until this driver list is used. This patch also introduces the flow_block_command and flow_block_binder_type enumerations, which are renamed to use FLOW_BLOCK_* in follow up patches. There are three definitions (aliases) in order to reduce the number of updates in this patch, which go away once drivers are fully adapted to use this flow block API.

From Neil Brown. 13) Allow tunneling with GUE encap in ipvs, from Jacky Hu. 14) Improve link partner cap detection in generic PHY code, from Heiner Kallweit. 15) Add layer 2 encap support to bpf_skb_adjust_room(), from Alan Maguire. 16) Remove SKB list implementation assumptions in SCTP, your's truly. 17) Various cleanups, optimizations, and simplifications in r8169 driver. From Heiner Kallweit. 18) Add memory accounting on TX and RX path of SCTP, from Xin Long. 19) Switch PHY drivers over to use dynamic featue detection, from Heiner Kallweit. 20) Support flow steering without masking in dpaa2-eth, from Ioana Ciocoi. 21) Implement ndo_get_devlink_port in netdevsim driver, from Jiri Pirko. 22) Increase the strict parsing of current and future netlink attributes, also export such policies to userspace. From Johannes Berg. 23) Allow DSA tag drivers to be modular, from Andrew Lunn. 24) Remove legacy DSA probing support, also from Andrew Lunn. 25) Allow ll_temac driver to be used on non-x86 platforms, from Esben Haabendal. 26) Add a generic tracepoint for TX queue timeouts to ease debugging, from Cong Wang. 27) More indirect call optimizations, from Paolo Abeni" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1763 commits) cxgb4: Fix error path in cxgb4_init_module net: phy: improve pause mode reporting in phy_print_status dt-bindings: net: Fix a typo in the phy-mode list for ethernet bindings net: macb: Change interrupt and napi enable order in open net: ll_temac: Improve error message on error IRQ net/sched: remove block pointer from common offload structure net: ethernet: support of_get_mac_address new ERR_PTR error net: usb: smsc: fix warning reported by kbuild test robot staging: octeon-ethernet: Fix of_get_mac_address ERR_PTR check net: dsa: support of_get_mac_address new ERR_PTR error net: dsa: sja1105: Fix status initialization in sja1105_get_ethtool_stats vrf: sit mtu should not be updated when vrf netdev is the link net: dsa: Fix error cleanup path in dsa_init_module l2tp: Fix possible NULL pointer dereference taprio: add null check on sched_nest to avoid potential null pointer dereference net: mvpp2: cls: fix less than zero check on a u32 variable net_sched: sch_fq: handle non connected flows net_sched: sch_fq: do not assume EDT packets are ordered net: hns3: use devm_kcalloc when allocating desc_cb net: hns3: some cleanup for struct hns3_enet_ring ...

| * | | net: move skb->xmit_more hint to softnet dataFlorian Westphal2019-04-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two reasons for this. First, the xmit_more flag conceptually doesn't fit into the skb, as xmit_more is not a property related to the skb. Its only a hint to the driver that the stack is about to transmit another packet immediately. Second, it was only done this way to not have to pass another argument to ndo_start_xmit(). We can place xmit_more in the softnet data, next to the device recursion. The recursion counter is already written to on each transmit. The "more" indicator is placed right next to it. Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more to check the "more packets coming" hint. skb->xmit_more is retained (but always 0) to not cause build breakage. This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/ conversions. Remaining drivers are converted in the next patches.

| * | | net: remove 'fallback' argument from dev->ndo_select_queue()Paolo Abeni2019-03-202-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the previous patch, all the callers of ndo_select_queue() provide as a 'fallback' argument netdev_pick_tx. The only exceptions are nested calls to ndo_select_queue(), which pass down the 'fallback' available in the current scope - still netdev_pick_tx. We can drop such argument and replace fallback() invocation with netdev_pick_tx(). This avoids an indirect call per xmit packet in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen) with device drivers implementing such ndo. It also clean the code a bit.
