net/mlx4_core: Respond to operation request by firmware

2013-07-29T08:12:40+00:00

This commit adds new firmware command and new firmware event.  The firmware
raises the MLX4_EVENT_TYPE_OP_REQUIRED event in order to signal the driver it
needs to perform an administrative operation throughout the MLX4_CMD_GET_OP_REQ
command. At the moment the supported operation is adding/removing multicast
entries which are used by the firmware for handling NCSI traffic in B0
steering mode.

Also, had to swap the order of mlx4_init_mcg_table() and
mlx4_init_eq_table() to make sure that driver will get events only after
resources are initialized to handle it.

net/mlx4_core: Dynamic VST to VST vlan/qos changes

2013-07-01T20:10:22+00:00

Within VST mode, enable modifying the vlan and/or qos
for a VF without requiring unbind/rebind.

This requires firmware which supports the UPDATE_QP command.
(If the command is not available, we fall back to requiring
unbind/bind to activate these changes).

To avoid race conditions with modify-qp on QPs that are affected
by update-qp, this operation is performed on the comm_wq.

If the update operation succeeds for all the necessary QPs, a
vlan_unregister is performed for the abandoned vlan id.

net/mlx4: Add set VF default vlan ID and priority support

2013-04-27T03:29:13+00:00

Add support to ndo_set_vf_vlan in the driver. Once this call is used the vport
is considered to be in VST mode. In this mode, the PPF driver configures
Ethernet QPs created by this VF to use this vlan id and priority. Currently
RoCE isn't supported on that mode.

The special values of VID=4095 or VID=0,UP=0 are considered as VGT.

net/mlx4_core: Add firmware commands to support device managed flow steering

2012-07-07T23:23:05+00:00

Add support for firmware commands to attach/detach a new device managed
steering mode. Such network steering rules allow the user to provide an
L2/L3/L4 flow specification to the firmware and have the device to steer
traffic that matches that specification to the provided QP.

mlx4_core: Modify driver initialization flow to accommodate SRIOV for Ethernet

2011-12-13T18:56:08+00:00

1. Added module parameters sr_iov and probe_vf for controlling enablement of
   SRIOV mode.
2. Increased default max num-qps, num-mpts and log_num_macs to accomodate
   SRIOV mode
3. Added port_type_array as a module parameter to allow driver startup with
   ports configured as desired.
   In SRIOV mode, only ETH is supported, and this array is ignored; otherwise,
   for the case where the FW supports both port types (ETH and IB), the
   port_type_array parameter is used.
   By default, the port_type_array is set to configure both ports as IB.
4. When running in sriov mode, the master needs to initialize the ICM eq table
   to hold the eq's for itself and also for all the slaves.
5. mlx4_set_port_mask() now invoked from mlx4_init_hca, instead of in mlx4_dev_cap.
6. Introduced sriov VF (slave) device startup/teardown logic (mainly procedures
   mlx4_init_slave, mlx4_slave_exit, mlx4_slave_cap, mlx4_slave_exit and flow
   modifications in __mlx4_init_one, mlx4_init_hca, and mlx4_setup_hca).
   VFs obtain their startup information from the PF (master) device via the
   comm channel.
7. In SRIOV mode (both PF and VF), MSI_X must be enabled, or the driver
   aborts loading the device.
8. Do not allow setting port type via sysfs when running in SRIOV mode.
9. mlx4_get_ownership:  Currently, only one PF is supported by the driver.
   If the HCA is burned with FW which enables more than one PF, only one
   of the PFs is allowed to run.  The first one up grabs a FW ownership
   semaphone -- all other PFs will find that semaphore taken, and the
   driver will not allow them to run.
