2011-12-13mlx4_core: Reduce number of PD bits to 17Jack Morgenstein
When SRIOV is enabled on the chip (at FW burning time), the HCA uses only 17 bits for the PD. The remaining 7 high-order bits are ignored. Change the allocator to return only 17 bits for the PD. The MSB 7 bits will be used to encode the slave number for consistency checking later on in the resource tracker. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: David S.

2011-12-13mlx4_core: Add "native" argument to mlx4_cmd and its callers (where needed)Jack Morgenstein
For SRIOV, some Hypervisor commands can be executed directly (native = 1). Others should go through the command wrapper flow (for tracking resource usage, for example, or for changing some HCA configurations that slaves need to be notified of). This patch sets the groundwork for this capability -- adding the correct value of "native" in each case. Note that if SRIOV is not activated, this parameter has no effect.

2011-12-13mlx4: Extanding port_mask functionalityJack Morgenstein
Port mask now has additional state. Port can be set as "none". In this case neither the mlx4_en or mlx4_ib drivers take ownership of the port. In multifunction mode there is an option to set the vfs as single ported devices. (in single function mode, both physical ports belong to same function) Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S.

2011-12-13mlx4_core: initial header-file changes for SRIOV supportJack Morgenstein
These changes will not affect module operation as yet. They are only to get some structs and enums in place for use by subsequent patches (making those smaller). Added here: * sriov state structs and inlines (mlx4_is_master/slave/mfunc) * comm-channel and vhcr support structures * enum values for new FW and comm-channel virtual commands (i.e., commands, passed via the comm channel to the PF-driver). * prototypes for many command wrapper functions (used by the PF context for processing FW commands passed to it by the VFs). * struct mlx4_eqe is moved from eq.c to mlx4.h (it will be used by other mlx4_core source files).

2011-12-13be2net: refactor/cleanup vf configuration codeSathya Perla
- use adapter->num_vfs (and not the module param) to store the actual number of vfs created. Use the same variable to reflect SRIOV enable/disable state. So, drop the adapter->sriov_enabled field. - use for_all_vfs() macro in VF configuration code - drop the "vf_" prefix for the fields of be_vf_cfg; the prefix is redundant and removing it helps reduce line wrap Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2011-12-13be2net: fix ethtool ringparam reportingSathya Perla
The ethtool "-g" option is supposed to report the max queue length and user modified queue length for RX and TX queues. be2net doesn't support user modification of queue lengths. So, the correct values for these would be the max numbers. be2net incorrectly reports the queue used values for these fields.

2011-12-12xen-netfront: delay gARP until backend switches to ConnectedLaszlo Ersek
After a guest is live migrated, the xen-netfront driver emits a gratuitous ARP message, so that networking hardware on the target host's subnet can take notice, and public routing to the guest is re-established. However, if the packet appears on the backend interface before the backend is added to the target host's bridge, the packet is lost, and the migrated guest's peers become unable to talk to the guest. A sufficient two-parts condition to prevent the above is: (1) ensure that the backend only moves to Connected xenbus state after its hotplug scripts completed, ie. the netback interface got added to the bridge; and (2) ensure the frontend only queues the gARP when it sees the backend move to Connected. These two together provide complete ordering. Sub-condition (1) is already satisfied by commit f942dc2552b8 in Linus' tree, based on commit 6b0b80ca7165 from [1]. In general, the full condition is sufficient, not necessary, because, according to [2], live migration has been working for a long time without satisfying sub-condition (2). However, after 6b0b80ca7165 was backported to the RHEL-5 host to ensure (1), (2) still proved necessary in the RHEL-6 guest. This patch intends to provide (2) for upstream.

2011-12-07ath9k: use config.enable_ani to check if ani should be performedNikolay Martynov
Currently in ath9k code there is an attempt which is meant to disable ANI for ar9100 and ar9340. But it doesn't really achieve this. All it does is disable ANI init and setup (i.e. calls to ath9k_hw_ani_setup and ath9k_hw_ani_init). Since ath9k_hw_ani_setup is not called ah->config.ani_poll_interval is never initialized (i.e. it is always zero) and ath_ani_calibrate always executes ANI procedures (over uninitialized ANI parameters). Moreover, ath_ani_calibrate is being called each 1ms because common->ani.timer is set to zero interval because ah->config.ani_poll_interval==0 (and thus smallest value of all intervals). Normally it should not be called this often. This patch changes the code so config.enable_ani is used to check if ANI should be performed. config.enable_ani is initialized to true by default.
