Michael Chan noted that there is nothing in the code that would prevent the compiler from delaying the access of the "mapping" member of the newly arrived packet until much later. If this happened after the skb = NULL assignment, it is possible for the driver to pass a bad dma_addr value to pci_unmap_single(). To enforce this ordering, we need a write memory barrier.

2010-02-12tg3: Unwedge stuck MSI-X vectorsMatt Carlson1-10/+19
The previous patch changed the code so that new rx buffer submissions to the hardware stall if a new submission would overwrite data needed by an unserviced rx packet. On very busy 5717 and 57765 asic rev devices, there is a corner case where the hardware will fail to assert an MSI-X interrupt for rx traffic. If that vector's interrupt never has another reason to assert, any rx buffers held will never be serviced. If the buffers are never serviced and the hardware consumes all the available rx packets for other rx rings, deadlock will result. The most reliable and least intrusive way to work around the problem is to detect the case where new submissions would overwrite existing data and force all rx interrupt vectors to fire.

2010-01-13tg3: Fix std rx prod ring handlingMatt Carlson1-2/+3
There are some tg3 devices that require the driver to post new rx buffers in smaller increments. Commit 4361935afe3abc3e5a93006b99197fac1fabbd50, "tg3: Consider rx_std_prod_idx a hw mailbox" changed how the driver tracks the rx producer ring updates, but it does not make any special considerations for the above-mentioned devices. For those devices, it is possible for the driver to hit the special case path, which updates the hardware mailbox register but skips updating the shadow software mailbox member. If the special case path represents the final mailbox update for this ISR iteration, the hardware and software mailbox values will be out of sync. Ultimately, this will cause the driver to use a stale mailbox value on the next iteration, which will appear to the hardware as a large rx buffer update. Bad things ensue. The fix is to update the software shadow mailbox member when the special case path is taken.
