drivers/net/lib8390: fix warning, trim trailing whitespace
fix drivers/net/lib8390.c: In function ‘ei_tx_err’: drivers/net/lib8390.c:556: warning: unused variable ‘ei_local’ drivers/net/lib8390.c: In function ‘ei_rx_overrun’: drivers/net/lib8390.c:819: warning: unused variable ‘ei_local’ and also trim whitespace.

* card means that approach caused horrible problems like losing serial data

* at 38400 baud on some chips. Remember many 8390 nics on PCI were ISA

* chips with FPGA front ends.

|

* Ok the logic behind the 8390 is very simple:
|
||||
*
|
||||
*
|
||||
* Things to know
|
||||
* - IRQ delivery is asynchronous to the PCI bus
|
||||
* - Blocking the local CPU IRQ via spin locks was too slow
|
||||
* - The chip has register windows needing locking work
|
||||
*
|
||||
*
|
||||
* So the path was once (I say once as people appear to have changed it
|
||||
* in the mean time and it now looks rather bogus if the changes to use
|
||||
* disable_irq_nosync_irqsave are disabling the local IRQ)
|
||||

*
|
||||

|

|
||||
* Take the page lock
|
||||
* Mask the IRQ on chip
|
||||
* Disable the IRQ (but not mask locally- someone seems to have

* [This must be _nosync as the page lock may otherwise
|

* deadlock us]
|
||||
* Drop the page lock and turn IRQs back on
|
||||
*
|
||||
*
|
||||
* At this point an existing IRQ may still be running but we can't
|
||||
* get a new one
|

*
|
||||
*
|
||||
* Take the lock (so we know the IRQ has terminated) but don't mask

* the IRQs on the processor
|

* Set irqlock [for debug]

* Transmit (slow as ****)
|

|

|

* re-enable the IRQ
|

*
|

*
|

*
|
||||
* We have to use disable_irq because otherwise you will get delayed
|
||||
* interrupts on the APIC bus deadlocking the transmit path.
|
||||
*
|
||||
*
|
||||
* Quite hairy but the chip simply wasn't designed for SMP and you can't
|
||||
* even ACK an interrupt without risking corrupting other parallel
|
||||
* activities on the chip." [lkml, 25 Jul 2007]
