Driver crashes if the BIOS do not set up at least one
memory I/O resource. This failure can happen if the device is too
slow to respond during POST and is missed by the BIOS, but Linux

Since cmds go into qla_tgt_wq and TMRs don't, it's possible that TMR

To avoid this race, use a per-port list to keep track of cmds that
are enqueued to qla_tgt_wq but not yet processed. When a TMR arrives,

To fix some issues talking to ESX, this patch modifies the qla2xxx driver
so that it never logs into remote ports. This has the side effect of

When ipr's internal driver trace was changed to an atomic, a signed/unsigned
bug slipped in which results in us indexing backwards in our memory buffer
writing on memory that does not belong to us. This patch fixes this by removing
the modulo and instead just mask off the low bits.
