8139x: reduce message severity on driver overlap

2008-10-22T11:00:28+00:00

The 8139 drivers are a source of error messages that confuse users.

Since this device can not be disambiguated by normal PCI device
id's two drivers match the same info. But the module utilities
seem to correctly handle this overlap, they try one driver, then
if that doesn't load try the other. Therefore there is no need for
a message to be logged with error level severity, just using info
level instead. Can't be completely silent because user might have
configure one driver and forgot the other one.

8139too: move wmb before TX DMA start

2008-10-09T00:12:57+00:00

The write barrier should be used before starting a DMA transfer. This fixes
a problem, where almost all packets received on another machine had garbled
content. Tested with an RTL8100C on a MIPS machine.

8139too: [cosmetic] fix incorrect register for flash-rom

2008-09-24T22:49:05+00:00

I would like to submit a correction to the driver

     drivers/net/8139too.c,

which in no way changes the compiled driver, but does change
the value of a previously incorrect value for the configuration
register address of Flash PROM on the network processor rtl8139C.
This corrected value is in accordance with the datasheet
for rtl8139C, and in addition this new value is indeed used
in other functional drivers that use this adapter for
programming a Flash memory chip in situ. But as said,
the two new constants are never referenced in the driver
maintained by you: they are only informational and correct!

8139too: use netdev_alloc_skb

2008-09-03T14:24:14+00:00

This patch uses netdev_alloc_skb. This sets skb->dev and allows
arch specific allocation. Also cleanup the alignment code.

8139too: Force usage of PIO on OQO2

2008-07-22T21:59:26+00:00

The OQO model 2 has an RTL8139 from Atheros that doesn't like MMIO.
It fails on modprobe, with a 'PCI Bus error' message.

Force it to always use polled IO.

8139too: Make PIO/MMIO a runtime decision through a module parameter.

2008-07-22T21:59:21+00:00

This is needed to support devices that only work with PIO without
penalising devices that work fine with MMIO in distro kernels.
It also allows us to eventually use PIO as a fallback when setting
up MMIO fails.

[netdrvr] kill sync_irq-before-freq_irq pattern

2008-06-28T14:23:38+00:00

synchronize_irq() is superfluous when free_irq() call immediately follows it,
because free_irq() also does a synchronize_irq() call of its own.

8139too: some style cleanups

2008-06-28T14:23:35+00:00

Clean up the following errors and warnings reported by checkpatch.pl:
 + ERROR: Macros with complex values should be enclosed in parenthesis
 + WARNING: __func__ should be used instead of gcc specific __FUNCTION__
 + WARNING: plain inline is preferred over __inline__
 + WARNING: Use #include  instead of

The changes were verified with by comparing the "objdump -d 8139too.ko"
output which is exactly the same for the old and new version in case of

CONFIG_8139TOO_8129=n, CONFIG_8139_OLD_RX_RESET=n.
