net/mlx4: Spoofcheck and zero MAC can't coexist

2017-02-23T15:57:56+00:00

Spoofcheck can't be enabled if VF MAC is zero.
Vice versa, can't zero MAC if spoofcheck is on.

net/mlx4_core: Keep VLAN/MAC tables mirrored in multifunc HA mode

2015-12-07T03:40:45+00:00

Due to HW limitations, indexes to MAC and VLAN tables are always taken
from the table of the actual port. So, if a resource holds an index to
a table, it may refer to different values during the lifetime of the
resource,  unless the tables are mirrored. Also, even when
driver is not in HA mode the policy of allocating an index to these
tables is such to make sure, as much as possible, that when the time
comes the mirroring will be successful. This means that in multifunction
mode the allocation of a free index in a port's table tries to make sure
that the same index in the other's port table is also free.

net/mlx4: Postpone the registration of net_device

2015-08-30T22:12:20+00:00

The mlx4 network driver was registered in the context of the 'add'
function of the core driver (called when HW should be registered).
This makes the netdev event NETDEV_REGISTER to be sent in a context
where the answer to get_protocol_dev() callback returns NULL. This may
be confusing to listeners of netdev events.
This patch is a preparation to the patch that implements the
get_netdev() callback in the IB/mlx4 driver.

net/mlx4_core: Port aggregation upper layer interface

2015-02-05T00:14:24+00:00

Supply interface functions to bond and unbond ports of a mlx4 internal
interfaces. Example for such an interface is the one registered by the
mlx4 IB driver under RoCE.

There are

1. Functions to go in/out to/from bonded mode
2. Function to remap virtual ports to physical ports

The bond_mutex prevents simultaneous access to data that keep status of
the device in bonded mode.

The upper mlx4 interface marks to the mlx4 core module that they
want to be subject for such bonding by setting the MLX4_INTFF_BONDING
flag. Interface which goes to/from bonded mode is re-created.

The mlx4 Ethernet driver does not set this flag when registering the
interface, the IB driver does.

net/mlx4: Replace mlx4_en_mac_to_u64() with mlx4_mac_to_u64()

2014-03-03T01:04:01+00:00

Currently, the EN driver uses a private static function
mlx4_en_mac_to_u64(). Move it to a common include file (driver.h)
for mlx4_en and mlx4_ib for further use.

IB/mlx4: Initialize SR-IOV IB support for slaves in master context

2012-10-01T03:33:32+00:00

Allocate SR-IOV paravirtualization resources and MAD demuxing contexts
on the master.

This has two parts.  The first part is to initialize the structures to
contain the contexts.  This is done at master startup time in
mlx4_ib_init_sriov().

The second part is to actually create the tunneling resources required
on the master to support a slave.  This is performed the master
detects that a slave has started up (MLX4_DEV_EVENT_SLAVE_INIT event
generated when a slave initializes its comm channel).

For the master, there is no such startup event, so it creates its own
tunneling resources when it starts up.  In addition, the master also
creates the real special QPs.  The ib_core layer on the master causes
creation of proxy special QPs, since the master is also
paravirtualized at the ib_core layer.
