This driver uses that hardware queue size for the Rx ring, where a large number of entries has no ill effect beyond increases the potential backlog.

These forward-looking statements are based on current expectations, forecasts and assumptions and involve a number of risks and uncertainties that could cause actual results to differ materially from those anticipated by these forward-looking statements. The Tx ring is wrapped with the END bit, since a large hardware Tx queue disables the queue layer priority ordering and we have no mechanism to utilize the hardware two-level priority queue.

Synchronization The driver runs as two independent, single-threaded flows of control. Adaptec expressly disclaims any obligation ada;tec update forward-looking statements, whether as a result of new information, future events or otherwise. Buffers consumed this way are replaced by newly allocated skbuffs in a later phase of receive. The Tx ring is wrapped with the END bit, since a large hardware Tx queue disables the queue layer priority ordering and we have no mechanism to utilize the hardware two-level priority queue.
I was very impressed with the performance, scalability, and reliability of the Adaptec SAS technology. Maxtor and its products can be found at www.
Unlike software-only systems, device drivers interact with complex hardware. Please send all bug reports to me, and not to Donald Becker, as this code has been heavily modified from Donald’s original version. However in some modes a descriptor may be marked to wrap the ring earlier. Forward-looking statements include statements regarding future events or the future performance of Adaptec. When the incoming frame is larger, the skbuff is passed directly up the protocol stack.
The driver does not use the completion queue consumer index, but instead checks for non-zero status entries.

The ring sizes are set fixed by the hardware, but may optionally be wrapped earlier by the END bit in the descriptor. These may be modified when a driver module is loaded.
Is SAS really better or is the industry just telling us it is? In general, only the important configuration values or bits changed multiple times should be defined symbolically. Thus the IP header at offset 14 in an ethernet frame isn’t longword aligned, which may cause problems on some machine e.
Should we add a busy-wait here? A notable aspect of operation is that unaligned buffers are not permitted by the Starfire hardware. Setting the Rx and Tx modes. It’s not useful to define symbolic names for every register bit in the device.

The driver allocates full frame size skbuffs for the Rx ring buffers, so all frames should fit in a single descriptor. ADPT provides trusted storage solutions that reliably move, manage, and protect critical data and digital content. There are redundant checks here that may be cleaned up after the driver has proven to be reliable.

Handle allocation failure gracefully. For these architectures, the driver is 1503bb to copy the frame into a new skbuff unconditionally.
