2012-07-10bnx2: Fix bug in bnx2_free_tx_skbs().Michael Chan1-3/+3
In rare cases, bnx2x_free_tx_skbs() can unmap the wrong DMA address when it gets to the last entry of the tx ring. We were not using the proper macro to skip the last entry when advancing the tx index.

2012-07-10net/mlx4_core: Initialize IB port capabilities for all slavesJack Morgenstein1-0/+11
With IB SR-IOV, each slave has its own separate copy of the port capabilities flags. For example, the master can run a subnet manager (which causes the IsSM bit to be set in the master's port capabilities) without affecting the port capabilities seen by the slaves (the IsSM bit will be seen as cleared in the slaves). Also add a static inline mlx4_master_func_num() to enhance readability of the code.

2012-07-10mlx4: Use port management change event instead of smp_snoopJack Morgenstein5-69/+27
The port management change event can replace smp_snoop. If the capability bit for this event is set in dev-caps, the event is used (by the driver setting the PORT_MNG_CHG_EVENT bit in the async event mask in the MAP_EQ fw command). In this case, when the driver passes incoming SMP PORT_INFO SET mads to the FW, the FW generates port management change events to signal any changes to the driver. If the FW generates these events, smp_snoop shouldn't be invoked in ib_process_mad(), or duplicate events will occur (once from the FW-generated event, and once from smp_snoop). In the case where the FW does not generate port management change events smp_snoop needs to be invoked to create these events. The flow in smp_snoop has been modified to make use of the same procedures as in the fw-generated-event event case to generate the port management events (LID change, Client-rereg, Pkey change, and/or GID change). Port management change event handling required changing the mlx4_ib_event and mlx4_dispatch_event prototypes; the "param" argument (last argument) had to be changed to unsigned long in order to accomodate passing the EQE pointer. We also needed to move the definition of struct mlx4_eqe from net/mlx4.h to file device.h -- to make it available to the IB driver, to handle port management change events.

commit db83d136d7f753 (gianfar: Fix missing sock reference when processing TX time stamps) added a potential sk_wmem_alloc imbalance If the new skb has a different truesize than old one, we can get a negative sk_wmem_alloc once new skb is orphaned at TX completion. Now we no longer early orphan skbs in dev_hard_start_xmit(), this probably can lead to fatal bugs.

Macro spin_event_timeout() was designed for simple polling of hardware registers with a timeout, so use it when we poll the MIIMIND register. This allows us to return an error code instead of polling indefinitely. Note that PHY_INIT_TIMEOUT is a count of loop iterations, so we can't use it for spin_event_timeout(), which asks for microseconds.
