be2net: fix spurious interrupt handling in intx mode

2009-07-04T03:09:45+00:00

Occasionally we may see an interrupt without an event in the eq.
In intx, we currently see the event queue and return IRQ_NONE causing
a the irq to be disabled ("no one cared".) Instead, read the CEV_ISR
reg to check the existence of the interrupt.

be2net: Fix to avoid a crash seen on PPC with LRO and Jumbo frames.

2009-06-29T00:34:25+00:00

While testing the driver on PPC, we ran into a crash with LRO, Jumbo frames.
With CONFIG_PPC_64K_PAGES configured (a default in PPC), MAX_SKB_FRAGS drops to 3 and we were crossing the array limits on skb_shinfo(skb)->frags[].
Now we coalesce the frags from the same physical page into one slot in
skb_shinfo(skb)->frags[] and go to the next index when the frag is from

different physical page.

This patch is against the net-2.6 tree.

be2net: Use MCC queue for cmds that may be called in BH context

2009-06-19T07:18:40+00:00

Currenlty multicast_set and promiscuous_config cmds -- that may be called in BH context --
use the blocking MCC mbox to post cmds.
An mbox cmd is protected via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable
to disable BHs while a blocking mbox cmd is in progress (and take long to finish.)
This can lockup a cmd in progress in process context.
So, these two cmds in BH context must use the MCC queue to post cmds.

be2net: Add MCC queue mechanism for BE cmds

2009-06-19T07:18:39+00:00

Currenlty all cmds use the blocking MCC mbox to post cmds. An mbox cmd is protected
via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable
to disable BHs while a blocking mbox cmd is in progress (and take long to finish.)
This can lockup a cmd in progress in process context. Instead cmds that may be
called in BH context must use the MCC queue to post cmds. The cmd completions
are rcvd in a separate completion queue and the events are placed in the tx-event
queue.

be2net: Fix be_tx_q_clean() being called on freed queues

2009-06-11T09:47:19+00:00

In the tx queue destroy path, be_tx_q_clean() is currently called after the tx queues are freed; it must be called before.

be2net: Fix early reset of rx-completion

2009-06-11T09:47:18+00:00

be_rx_compl_get() must not reset(via the valid word) the rx_compl as the rx_compl is not processed yet; it must be reset after it is processed.
