Reduce the frequency of polling for SFP modules. Because the service task sometimes runs at high rates, we can poll for SFPs too often. When an SFP is not present, the I2C timeouts that result are very costly. So, prevent SFP polling from being done more than once every two seconds. To reduce latency, the poll time is cleared in a couple of cases to permit the next service task execution to poll the SFP module. Signed-off-by:

Configures the CS4227 correctly for both 1G and 10G operation, by moving the code to ixgbe_setup_mac_link_sfp_x550em(). It needs to be in this function because we need both the module type and the speed, and this is the only function in the init flow that knows the speed. In contrast, ixgbe_setup_sfp_modules_X550em() does not know the speed, so we can't do anything useful here. This is a fundamental difference from the previous flow, and is due to the way the CS4227 is implemented. Signed-off-by:

This patch adds X550EM_x SFP+ dual-speed support. 82599 fiber link code was moved from ixgbe_82599.c to ixgbe_common.c for use by X550EM. SFP MAC link code is added to x550EM. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-09-22 This series contains updates to e1000, e1000e, igbvf, ixgbe, ixgbevf and fm10k. Jacob provides several updates for fm10k, which cleans up comments and most notably a fix for a corner case issue with the PF/VF mailbox code. The issue being fm10k_mbx_reset_work clears various states about the mailbox, but does not clear the Tx FIFO head/tail pointers. We also are not able to simply clear these pointers, as we would drop untransmitted messages without error. Also adds support for extra debug statistics, which provides the ability to see what the PF thinks the VF mailboxes look like. Don adds support for SFP+ in X550 and support for SCTP flow director filters SCTP mask. Francois Romieu dusts off the e1000 driver and removes some dead calls to e1000_init_eeprom_params(). Toshiaki Makita provides three patches to enable TSO for stacked VLAN's on e1000e, igbvf and ixgbevf. Mark provides the first of several ixgbe updates. First updates the driver to accept SFP not present error for all devices, since an SFP can still be inserted. Adds support for SFP insertion interrupt on X550EM devices with SPFs. Adds I2C combined operations on X550EM (not X550) devices. Moved the setting of lan_id to before any I2C eeprom access. Lastly, set the bit bang mode in the hardware when performing bit banding I2C operations on X550. ==================== Signed-off-by:

Scott Feldman says: ==================== bridge: don't age out externally added FDB entries v3: Per davem review: add del_timer_sync on rocker port remove. v2: Per Jiri review comment: add BR_DEFAULT_AGEING_TIME to defines Siva originally proposed skipping externally added FDB entries in the bridge's FDB garbage collection func, and moving the ageing of externally added entries to the port driver/device. This broke rocker, since rocker didn't have a hardware (or software) mechanism for ageing out its learned FDB entries. This patchset reintroduces Siva's bridge driver patch to skip externally added entries and adds support in rocker so rocker can age out its own entries. Rocker does this using a software timer similar to the bridge's FDB garbage collection timer. Other switchdev devices/drivers can use this software timer method or program the device to nofity aged-out entries to the driver. Updated switchdev.txt documentation to reflect current state-of-the-art. This removes one more XXX todo comment in switchdev.txt. ==================== Signed-off-by:

Jamal suggested to further limit the currently allowed subset of opcodes that may be used by a direct action return code as the intention is not to replace the full action engine, but rather to have a minimal set that can be used in the fast-path on things like ingress for some features that cls_bpf supports. Classifiers can, of course, still be chained together that have direct action mode with those that have a full exec pass. For more complex scenarios that go beyond this minimal set here, the full tcf_exts_exec() path must be used. Suggested-by:

The binding to a particular classid was so far always mandatory for cls_bpf, but it doesn't need to be. Therefore, lift this restriction as similarly done in other classifiers. Only a couple of qdiscs make use of class from the tcf_result, others don't strictly care, so let the user choose his needs (those that read out class can handle situations where it could be NULL). An explicit check for tcf_unbind_filter() is also not needed here, as the previous r->class was 0, so the xchg() will return that and therefore a callback to the qdisc's unbind_tcf() is skipped.

In commit 43388da42a49 ("cls_bpf: introduce integrated actions") we have added TCA_BPF_FLAGS. We can also retrieve this information from the prog, dump it back to user space as well. It's useful in tc when displaying/dumping filter info. Also, remove tp from cls_bpf_prog_from_efd(), came in as a conflict from a rebase and it's unused here (later work may add it along with a real user). Signed-off-by:

Similarly as already the case in bpf_redirect()/skb_do_redirect() pair, let the stack deal with devs that are !IFF_UP. dev_forward_skb() as well as dev_queue_xmit() will free the skb and increment drop counter internally in such cases, so we can spare the condition in bpf_clone_redirect().
