through these ChangeSets:
<dfarnsworth:mvista.com>:
o [netdrvr mv643xx] Big rename
o [netdrvr mv643xx] Rename MV_READ => mv_read and MV_WRITE => mv_write
o [netdrvr mv643xx] Additional whitespace cleanups, mostly changing spaces to
tabs in comments
o [netdrvr mv643xx] Run mv643xx_eth.[ch] through scripts/Lindent
o [netdrvr mv643xx] Add a function to detect at runtime whether a PHY is
attached to the specified port, and use it to cause the probe routine to fail
when there is no PHY.
o [netdrvr mv643xx] This one liner removes a spurious left paren fixing an
obvious syntax error in the #ifndef MV64340_NAPI case
o [netdrvr mv643xx] Add support for PHYs/boards that don't support
autonegotiation
o [netdrvr mv643xx] With this patch, the driver now calls
netif_carrier_off/netif_carrier_on
o [netdrvr mv643xx] This patch cleans up the handling of receive skb sizing
<mbrancaleoni:tiscali.it>:
o sis900.c net poll support
<takis:lumumba.luc.ac.be>:
o Possible VIA-Rhine free irq issue
Alexander Viro:
o fealnx iomem annotations, switch to io{read,write}
o wireless iomem annotations and fixes, switch to io{read,write}
Andrew Morton:
o VIA-Rhine: undork whitespace
Dale Farnsworth:
o mv643xx: remove superfluous function, mv643xx_set_ethtool_ops
o mv643xx: raise size of receive skbs to allow for an optional VLAN tag
o [netdrvr mv643xx] Remove call to msleep() while locks are held. We don't
really need to wait for the link to come up. It was a workaround to avoid a
transient error message, "Virtual device %s asks to queue packet!\n", in
dev_queue_xmit() when called by ic_bootp_send_if(). This happens because right
after opening the network device, there is a pending PHY status change
interrupt causing the driver to call netif_stop_queue(). A half second later,
the link comes up and all is well. We could have moved the call to msleep() to
mv643xx_eth_open() to perpetuate the workaround, but I think it's best to
remove it entirely.
o [netdrvr mv643xx] Ensure that we only change the Port Serial Control Reg
while the port is disabled.
o [netdrvr mv643xx] Add ethtool support to the mv643xx ethernet driver
o [netdrvr mv643xx] Enable the mv643xx ethernet support on platforms using
the MV64360 chip
o [netdrvr mv643xx] Disable tcp/udp checksum offload to hardware. It
generally works, but the hardware appears to generate the wrong checksum if the
hw checksum generation wasn't used in the previous packet sent.
o [netdrvr mv643xx] We already set ETH_TX_ENABLE_INTERRUPT whenever we set
ETH_TX_LAST_DESC
o [netdrvr mv643xx] Update tx_bytes statistic when using hw tcp/udp checksum
generation
o [netdrvr mv643xx] Call netif_carrier_off when closing the driver
o [netdrvr mv643xx] Trivial. Remove repeated comment
o [netdrvr mv643xx] Clear transmit l4i_chk even when the hardware ignores it
o [netdrvr mv643xx] Increment tx_ring_skbs before calling eth_port_send, since
o [netdrvr mv643xx] Fix handling of unaligned tiny fragments not handled by
hardware Check all fragments instead of just the last.
o [netdrvr mv643xx] Fix a few places I missed in the previous rename patch
o [netdrvr mv643xx] This patch simplifies the mv64340_eth_set_rx_mode
function without changing its behavior.
o [netdrvr mv643xx] This patch makes the use of the
MV64340_RX_QUEUE_FILL_ON_TASK config macro more consistent, though the macro
remains undefined, since the feature still does not work properly.
o [netdrvr mv643xx] This patch adds support for passing additional parameters
via the platform_device interface. These additional parameters are:
o [netdrvr mv643xx] This patch adds device driver model support to the
mv643xx_eth driver
o [netdrvr mv643xx] This patch replaces the use of the pci_map_* functions
with the corresponding dma_map_* functions.
o [netdrvr mv643xx] This patch fixes the code that enables hardware checksum
generation
o [netdrvr mv643xx] This patch removes spin delays (count to 1000000, ugh)
and instead waits with udelay or msleep for hardware flags to change.
o [netdrvr mv643xx] This patch removes code that is redundant or useless
Daniele Venzano:
o sis900: chiprev i/o cleanups
o sis900: debugging output update
o sis900 printk audit
o sis900: version bump; remove broken URL
o sis900: add infrastructure needed for standard netif messages
