This patch adds FW versions stored in the flash to devlink info_get callback. Return the correct fw.psid running version using the newly added bp->nvm_cfg_ver. v2: Ensure stored pkg_name string is NULL terminated when copied to devlink. Return directly from the last call to bnxt_dl_info_put(). If the FW call to get stored version fails for any reason, return success immediately to devlink without the stored versions. Reviewed-by:

Add a new function bnxt_dl_info_put() to simplify the code, as there are more stored firmware version fields to be added in the next patch. Also, rename fw_ver variable name to ncsi_ver for better naming while copying to devlink info_get cb. v2: Ensure active_pkg_name string is NULL terminated when copied to devlink. Return directly from the last call to bnxt_dl_info_put(). Reviewed-by:

Add a new bnxt_hwrm_nvm_get_dev_info() to query firmware version information via NVM_GET_DEV_INFO firmware command. Use it to get the running version of the NVM configuration information. This new function will also be used in subsequent patches to get the stored firmware versions. Reviewed-by:

If the VF virtual link is set to always enabled, the speed may be unknown when the physical link is down. The driver currently logs the link speed as 4294967295 Mbps which is SPEED_UNKNOWN. Modify the link up log message as "speed unknown" which makes more sense. Reviewed-by:

Currently, bp->msg_enable has default value of 0. It is more useful to have the commonly used NETIF_MSG_DRV and NETIF_MSG_HW enabled by default. v2: Change the fall back bnxt_reset_task() inside bnxt_rx_ring_reset() to silent mode. With older fw, we would take the fall back path and it would be very noisy. Reviewed-by:

Vladimir Oltean says: ==================== Offload tc-vlan mangle to mscc_ocelot switch This series offloads one more action to the VCAP IS1 ingress TCAM, which is to change the classified VLAN for packets, according to the VCAP IS1 keys (VLAN, source MAC, source IP, EtherType, etc). ==================== Signed-off-by: -

Create a test that changes a VLAN ID from 200 to 300. We also need to modify the preferences of the filters installed for the other rules so that they are unique, because we now install the "tc-vlan modify" filter in VCAP IS1 only temporarily, and we need to perform the deletion by filter preference number.

When the Extraction Frame Header contains a valid classified VLAN, use that instead of the VLAN header present in the packet. Signed-off-by:
-
Vladimir Oltean authored
The VCAP_IS1_ACT_VID_REPLACE_ENA action, from the VCAP IS1 ingress TCAM, changes the classified VLAN. We are only exposing this ability for switch ports that are under VLAN aware bridges. This is because in standalone ports mode and under a bridge with vlan_filtering=0, the ocelot driver configures the switch to operate as VLAN-unaware, so the classified VLAN is not derived from the 802.1Q header from the packet, but instead is always equal to the port-based VLAN ID of the ingress port. We _can_ still change the classified VLAN for packets when operating in this mode, but the end result will most likely be a drop, since both the ingress and the egress port need to be members of the modified VLAN. And even if we install the new classified VLAN into the VLAN table of the switch, the result would still not be as expected: we wouldn't see, on the output port, the modified VLAN tag, but the original one, even though the classified VLAN was indeed modified. This is because of how the hardware works: on egress, what is pushed to the frame is a "port tag", which gives us the following options: - Tag all frames with port tag (derived from the classified VLAN) - Tag all frames with port tag, except if the classified VLAN is 0 or equal to the native VLAN of the egress port - No port tag Needless to say, in VLAN-unaware mode we are disabling the port tag. Otherwise, the existing VLAN tag would be ignored, and a second VLAN tag (the port tag), holding the classified VLAN, would be pushed (instead of replacing the existing 802.1Q tag). This is definitely not what the user wanted when installing a "vlan modify" action. So it is simply not worth bothering with VLAN modify rules under other configurations except when the ports are fully VLAN-aware. Signed-off-by:

Claudiu Manoil says: ==================== enetc: Migrate to PHYLINK and PCS_LYNX Transitioning the enetc driver from phylib to phylink. Offloading the serdes configuration to the PCS_LYNX module is a mandatory part of this transition. Aiming for a cleaner, more maintainable design, and better code reuse. The first 2 patches are clean up prerequisites. Tested on a p1028rdb board. v2: validate() explicitly rejects now all interface modes not supported by the driver instead of relying on the device tree to provide only supported interfaces, and dropped redundant activation of pcs_poll (addressing Ioana's findings) ==================== Signed-off-by: -
Claudiu Manoil authored
This is a methodical transition of the driver from phylib to phylink, following the guidelines from sfp-phylink.rst. The MAC register configurations based on interface mode were moved from the probing path to the mac_config() hook. MAC enable and disable commands (enabling Rx and Tx paths at MAC level) were also extracted and assigned to their corresponding phylink hooks. As part of the migration to phylink, the serdes configuration from the driver was offloaded to the PCS_LYNX module, introduced in commit 0da4c3d3 ("net: phy: add Lynx PCS module"), the PCS_LYNX module being a mandatory component required to make the enetc driver work with phylink.

Move the skb_headroom check out of fr_hard_header and into pvc_xmit. This has two benefits: 1. Originally we only do this check for skbs sent by users on Ethernet- emulating PVC devices. After the change we do this check for skbs sent on normal PVC devices, too. (Also add a comment to make it clear that this is only a protection against upper layers that don't take dev->needed_headroom into account. Such upper layers should be rare and I believe they should be fixed.) 2. After the change we can simplify the parameter list of fr_hard_header. We no longer need to use a pointer to pointers (skb_p) because we no longer need to replace the skb inside fr_hard_header. Cc: Krzysztof Halasa <khc@pm.waw.pl> Signed-off-by:

The MTU setting for this DSA switch is global so we need to keep track of the MTU set for each port, then as soon as any MTU changes, roof the MTU to the biggest common denominator and poke that into the switch MTU setting. To achieve this we need a per-chip-variant state container for the RTL8366RB to use for the RTL8366RB-specific stuff. Other SMI switches does seem to have per-port MTU setting capabilities.

Johannes Berg says: ==================== netlink: export policy on validation failures Export the policy used for attribute validation when it fails, so e.g. for an out-of-range attribute userspace immediately gets the valid ranges back. v2 incorporates the suggestion from Jakub to have a function to estimate the size (netlink_policy_dump_attr_size_estimate()) and check that it does the right thing on the *normal* policy dumps, not (just) when calling it from the error scenario. v3 only addresses a few minor style issues. v4 fixes up a forgotten 'git add' ... sorry. v5 is a resend, I messed up v4's cover letter subject (saying v3) and apparently the second patch didn't go out at all. Tested using nl80211/iw in a few scenarios, seems to work fine and return the policy back, e.g. kernel reports: integer out of range policy: 04 00 0b 00 0c 00 04 00 01 00 00 00 00 00 00 00 ^ padding ^ minimum allowed value policy: 04 00 0b 00 0c 00 05 00 ff ff ff ff 00 00 00 00 ^ padding ^ maximum allowed value policy: 08 00 01 00 04 00 00 00 ^ type 4 == U32 for an out-of-range case. ==================== Signed-off-by: -

Add a new attribute NLMSGERR_ATTR_POLICY to the extended ACK to advertise the policy, e.g. if an attribute was out of range, you'll know the range that's permissible. Add new NL_SET_ERR_MSG_ATTR_POL() and NL_SET_ERR_MSG_ATTR_POL() macros to set this, since realistically it's only useful to do this when the bad attribute (offset) is also returned. Use it in lib/nlattr.c which practically does all the policy validation. v2: - add and use netlink_policy_dump_attr_size_estimate() v3: - remove redundant break v4: - really remove redundant break ... sorry Reviewed-by:
