mlx4: use netdev_rss_key_fill() helper

2014-11-16T20:59:13+00:00

Use of well known RSS key increases attack surface.
Switch to a random one, using generic helper so that all
ports share a common key.

Also provide ethtool -x support to fetch RSS key

net/mlx4: Set vlan stripping policy by the right command

2014-09-10T22:21:34+00:00

Changing the vlan stripping policy of the QP isn't supported by older
firmware versions for the INIT2RTR command. Nevertheless, we've used it.

Fix that by doing this policy change using INIT2RTR only if the firmware
supports it, otherwise, we call UPDATE_QP command to do the task.

net/mlx4_core: Add UPDATE_QP SRIOV wrapper support

2014-05-16T19:12:45+00:00

This patch adds UPDATE_QP SRIOV wrapper support.

The mechanism is a general one, but currently only source MAC
index changes are allowed for VFs.

net/mlx4_en: Use union for BlueFlame WQE

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

When BlueFlame is turned on, control segment of the TX WQE is changed,
and the second line of it is used for QPN.
Changed code to use a union in the mlx4_wqe_ctrl_seg instead of casting.
This makes the code clearer and solves the static checker warning:

drivers/net/ethernet/mellanox/mlx4/en_tx.c:839 mlx4_en_xmit()
	warn: potential memory corrupting cast 4 vs 2 bytes

net/mlx4_core: Add basic support for TCP/IP offloads under tunneling

2013-12-31T19:31:43+00:00

Add the low-level device commands and definitions used for TCP/IP HW offloads
of tunneled/vxlan traffic which are supported by the ConnectX3-pro NIC.

This is done through the following elements:

 - read tunneling device caps in QUERY_DEV_CAP
 - add helper function to do SET_PORT for tunneling
 - add DMFS VXLAN steering rule definitions
 - add CQE and WQE checksum offload field definitions

include: Convert ethernet mac address declarations to use ETH_ALEN

2013-08-02T19:33:54+00:00

It's convenient to have ethernet mac addresses use
ETH_ALEN to be able to grep for them a bit easier and
also to ensure that the addresses are __aligned(2).

Add #include  as necessary.

net/mlx4_core: Add HW enforcement to VF link state

2013-07-01T20:10:57+00:00

When the firmware supports the UPDATE_QP command, if the VF link is disabled,
block all QPs opened by the VF, by programming the UPDATE_QP command to drop
all RX & TX traffic to/from these QPs. Operates only in VST mode.

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: Strengthen VLAN tags/priorities enforcement in VST mode

2013-05-11T23:12:44+00:00

Make sure that the following steps are taken:

- drop packets sent by the VF with vlan tag
- block packets with vlan tag which are steered to the VF
- drop/block tagged packets when the policy is priority-tagged
- make sure VLAN stripping for received packets is set
- make sure force UP bit for the VF QP is set

Use enum values for all the above instead of numerical bit offsets.

IB/mlx4: Support memory window binding

2013-02-25T18:44:32+00:00

* Implement memory windows binding in mlx4_ib_post_send.

* Implement mlx4_ib_bind_mw by deferring to mlx4_ib_post_send.

* Rename MLX4_WQE_FMR_PERM_* flags to MLX4_WQE_FMR_AND_BIND_PERM_*,
  indicating that they are used both for fast registration work
  requests, and for memory window bind work requests.
