Subject: [RFC PATCH 4/4] ixgbe: Adding VSI support to ixgbe
This adds initial base support for VSI interfaces to the ixgbe
driver.
This supports up to 32 VSIs per physical function with each VSI
supporting up to 4 TX/RX queue pairs. The hardware has support
for modes using 2 queue pairs that enable up to 64 VSIs but they
are not enabled here. VSIs can be instantiated with 1,2, or 4
queues unfortunately due to hardware restrictions related to RSS
masking across queues 3 TX/RX queues is not supported. If a user
inputs a queue parameter of 3 for either TX or RX the vsi_add
will fail with EINVAL and a message will be printed to dmesg
explaining the error. EBUSY is returned if more than 32 VSIs are
added.
The driver uses a bitmask added to the ixgbe_adapter struct to
track VSIs. VSIs spawn net devices that can be independently
managed via their own ndo and ethtool ops.
Currently, MAC addresses must be added manually via 'ip link set'
or similar configuration (netlink) commands before bringing the
spawned devices online. I could easily generate random MAC addresses
if that is prefered although not required in my use case and seems
a bit arbitrary. I expect most users have a pool of known "good"
MAC addresses they can use or for testing can simply pick their
favorite address.
Additionally VSIs do not support promisc mode. It is not clear
to me at least what promiscuous mode means when the VSI is behind
a non-learning embedded bridge wich does not do flooding. The
hardware does not support flooding on the embedded bridge however
it does support mirroring which could be enabled to get something
that looks like promiscuous mode. Currently there is no kernel
support (netlink cmd?) to configure mirroring.
The embedded bridge that connects VSIs looks like an edge relay
in IEEE std terms. And can support both VEB and VEPA modes which
are managed independently of VSIs through the {set|get} bridge
APIs.
VSIs only support a single MAC addresses in this patch. This
is a software limitation and can/will be extended in subsequent
patches. For now a single MAC addresses is supported.
NOTE:
The SRIOV and VMDQ flags in ixgbe seem to be a bit overloaded
and convoluted. This patch uses these flags. A follow up patch
could clean up the ixgbe flag usage scheme.
RFC TODO: I'll complete these before sending the real patch
(1) interop with DCB/FCOE/SR-IOV
(2) vmdq_netdev can be dropped from tx_ring and just use
correctly set netdev. In slowpath we can look up management
netdev via vadapter->real_adapter->netdev and save the hotpath
vmdq_netdev if/else branch.
Otherwise I've been adding/delete VSIs with multiple netperf
TCP sessions without any crashes but I still need to do some
more testing.
