2011-11-16sky2: reduce default Tx ring sizestephen hemminger
The default Tx ring size for the sky2 driver is quite large and could cause excess buffer bloat for many users. The minimum ring size possible and still allow handling the worst case packet on 64bit platforms is 38 which gets rounded up to a power of 2. But most packets only require a couple of ring elements.

2011-11-16sky2: rename up/down functionsstephen hemminger
The code is clearer if the up/down functions are renamed to open/close like other drivers. Purely syntax change. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-16sky2: pci posting issuesstephen hemminger
A couple of the reset and setup paths have possible PCI posting issues. When setting registers, a read is necessary to force the writes to complete. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-16sky2: fix hang on shutdown (and other irq issues)stephen hemminger
There are several problems with recent change to how IRQ's are setup. * synchronize_irq in sky2_shutdown would hang because there was no IRQ setup. * when device was set to down, some IRQ bits left enabled so a hardware error would produce IRQ with no handler * quick link on Optima chip set was enabled without handler * suspend/resume would leave IRQ on with no handler if device was down Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2011-11-08sweep the floors and convert some .get_drvinfo routines to strlcpyRick Jones
Per the mention made by Ben Hutchings that strlcpy is now the preferred string copy routine for a .get_drvinfo routine, do a bit of floor sweeping and convert some of the as-yet unconverted ethernet drivers to it.

2011-11-04sky2: fix regression on Yukon Optimastephen hemminger
Changes to support other Optima types, introduced an accidental regression that caused 88E8059 to come up in 10Mbit/sec. The Yukon Optima supports a reverse auto-negotiation feature that was incorrectly setup, and not needed. The feature could be used to allow wake-on-lan at higher speeds. But doing it correctly would require other changes to initialization. Reported-by: Pavel Mateja <pavel@netsafe.cz> Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2011-10-19net: add skb frag size accessorsEric Dumazet
To ease skb->truesize sanitization, its better to be able to localize all references to skb frags size. Define accessors : skb_frag_size() to fetch frag size, and skb_frag_size_{set|add|sub}() to manipulate it. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2011-09-27sky2: manage irq better on single port cardstephen hemminger
Most sky2 hardware only has a single port, although some variations of the chip support two interfaces. For the single port case, use the standard Ethernet driver convention of allocating IRQ when device is brought up rather than at probe time. Also, change the error handling of dual port cards so that if second port can not be brought up, then just fail. No point in continuing, since the failure is most certainly because of out of memory. The dual port sky2 device has a single irq and a single status ring, therefore it has a single NAPI object shared by both ports.
