The limitation of the number of multicast address for VF is not enough for the large scale server with SR-IOV feature. IPv6 requires the multicast MAC address for each IP address to handle the Neighbor Solicitation message. We couldn't assign over 30 IPv6 addresses to a single VF. This patch introduces the new mailbox API, IXGBE_VF_UPDATE_XCAST_MODE, to update multicast mode of VF. This adds 3 modes; - NONE only L2 exact match addresses or Flow Director enabled - MULTI BAM and ROMPE set - ALLMULTI BAM, ROMPE and MPE set If a guest VF user wants over 30 MAC multicast addresses, set IFF_ALLMULTI to request PF to update xcast mode to enable VF multicast promiscuous mode. On the other hand, enabling VF multicast promiscuous mode may affect security and performance in the network of the NIC. Only trusted VF can enable multicast promiscuous mode. The behavior of untrusted VF is the same as previous version. Signed-off-by:

Implements the new netdev op to trust VF in ixgbe. The administrator can turn on and off VF trusted by ip command which supports trust message. # ip link set dev eth0 vf 1 trust on or # ip link set dev eth0 vf 1 trust off Send a ping to reset VF on changing the status of trusting. VF driver will reconfigure its features on reset. Signed-off-by:

Add netlink directives and ndo entry to trust VF user. This controls the special permission of VF user. The administrator will dedicatedly trust VF user to use some features which impacts security and/or performance. The administrator never turn it on unless VF user is fully trusted.

The commit 3092e5e4cc79 ("i40e: add little endian conversion for checksum") fixed the checksum bug on big-endian architecture. But we should not execute cpu_to_le16() unconditionally. Thus, put cpu_to_le16() under certain condition.

In i40evf_msix_aq(), the first two lines of rd32() are mainly to clear the registers. If we initialize 'val' at this point, it will be overwritten immediately. We shall simply discard the return value here. When we initialize 'val', we might as well include the mask in one step. Signed-off-by:

If a call to enable SR-IOV in the kernel failed, we need to disable I40E_FLAG_VEB_MODE_ENABLED, so that bridge mode could fall back to VEPA, which is a default. Change-ID: I12b6f776769506db85b29bea94b9c88d0b5ee65e Signed-off-by:

This patch fixes a problem where the driver output of the OEM version string varied from the other tools. The mask value and the order of operations were incorrect, per the original change request. Without this patch, the version string will appear incorrect from the driver. Change-ID: Ie1ca6485284b4ce3b57e5a99b18b7641617c7ef7 Signed-off-by:

This patch fixes a problem of possibly getting inconsistent flow control statuses after a PF reset. Requested_mode was being set with a default value during probing, but the initial HW state could be different from this mode. Change-ID: I772bf07b78616e87086418d4bd87954b66fa17cd Signed-off-by:

Not sure how this compiles at all. Use the correct struct for manipulating the VLAN filter list. Without this, the VLAN filter list doesn't get processed correctly, and VLAN filters will not be re-enabled after any kind of reset. Change-ID: Iceff2dc089f303058fb71ecb08419eed471e0e90 Signed-off-by:

This patch adds a workaround to drop any flow control frames from being transmitted from any VSI. FW can still send flow control frames if flow control is enabled. With this patch in place a malicious VF cannot send flow control or PFC packets out on the wire. Change-ID: I4303b24e98b93066d2767fec24dfe78be591c277 Signed-off-by:

Currently adding a new ipv4 address always cause the creation of the related network route, with default metric. When a host has multiple interfaces on the same network, multiple routes with the same metric are created. If the userspace wants to set specific metric on each routes, i.e. giving better metric to ethernet links in respect to Wi-Fi ones, the network routes must be deleted and recreated, which is error-prone. This patch implements the support for IFA_F_NOPREFIXROUTE for ipv4 address. When an address is added with such flag set, no associated network route is created, no network route is deleted when said IP is gone and it's up to the user space manage such route. Signed-off-by:

Vivien Didelot says: ==================== net: dsa: implement port_fdb_dump in drivers Not all switch chips provide a Get Next kind of operation to dump FDB entries. It is preferred to let the driver handle the dump operation the way it works best for the chip. Thus, drop port_fdb_getnext and implement the port_fdb_dump operation in DSA, which pushes the switchdev FDB dump callback down to the drivers. mv88e6xxx is the only driver affected and is updated accordingly. v3 -> v4: fix rejects on latest net-next v2 -> v3: opencode switchdev_obj_dump_cb_t to avoid multiple typedef; use ether_addr_copy in fdb_dump v1 -> v2: fix a few "return err" instead of "goto unlock" in mv88e6xxx.c ==================== Signed-off-by: -

There is no need to write the MAC address before every Get Next operation, since ATU MAC registers are not cleared between calls. Move the _mv88e6xxx_atu_mac_write call outside of _mv88e6xxx_atu_getnext so future code could call ATU Get Next multiple times and save a few register access. Signed-off-by: -
