In the xmit path, the driver may drop some pkts due to reasons such as DMA mapping errors, out of memory conditions or to protect HW from unrecoverable errors. Add a counter in TX-stats for such drops. Signed-off-by: NSathya Perla <sathya.perla@emulex.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The current EQ delay calculation for AIC is based only on RX packet rate. This fails to be effective when there's only TX and no RX. This patch inclues: - Calculating EQ-delay based on both RX and TX pps. - Modifying EQ-delay of all EQs via one cmd, instead of issuing a separate cmd for each EQ. - A new structure to store interrupt coalescing parameters, in a separate cache-line from the EQ-obj.

There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

commit e49cc34f introduced an unconditional IRQ_HANDLED return in be_intx() to workaround Lancer and BE2 HW issues. This is bad as it prevents the kernel from detecting interrupt storms due to broken HW. The BE2/Lancer HW issues are: 1) In Lancer, there is no means for the driver to detect if the interrupt belonged to device, other than counting and notifying events. 2) In Lancer de-asserting INTx takes a while, causing the INTx irq handler to be called multiple times till the de-assert happens. 3) In BE2, we see an occasional interrupt even when EQs are unarmed. Issue (1) can cause the notified events to be orphaned, if NAPI was already running. This patch fixes this issue by scheduling NAPI only if it is not scheduled already. Doing this also takes care of possible events_get() race that may be caused due to issue (2) and (3). Also, IRQ_HANDLED is returned only the first time zero events are detected.

The RX CQ can report completions with invalid frag_idx when the RXQ that was *previously* using it, was not cleaned up properly. This hits a BUG_ON() in be2net. When completion coalescing is enabled on a CQ, an explicit CQ-notify (with rearm) is needed for each compl, to flush partially coalesced CQ entries that are pending DMA. In be_close(), this fix now notifies CQ for each compl, waits explicitly for the flush compl to arrive and complains if it doesn't arrive. Also renaming be_crit_error() to be_hw_error() as it's the more appropriate name and to convey that we don't wait for the flush compl only when a HW error has occurred.
