[PATCH] sky2: receive queue watermark tweak

2006-12-07T09:58:33+00:00

This patch makes the receive performance on some systems go from
714MB/s to 941MB/s. It adjusts the watermark of the receive queue
to be lower, thereby avoiding excess hardware flow control. This is
most important on the systems which have little/no additional buffering.

[PATCH] sky2: msi enhancements.

2006-12-02T05:22:30+00:00

If using Message Signaled Interrupts (MSI) then the IRQ will never
be shared. Don't call pci_disable_msi() unless using MSI.

[PATCH] sky2: fixes for Yukon EC_U chip revisions

2006-12-02T05:22:29+00:00

Update workarounds for 88E803X based on the latest SysKonnect vendor
driver version (8.41). Tested on EC_U rev A1, only.
These up the receive performance.

sky2: GMAC pause frame

2006-10-17T17:24:25+00:00

This reverts earlier change that attempted to fix flow control.
Device needs to discard pause frames, otherwise it hangs after a while.

sky2: flow control setting fixes

2006-10-17T17:24:13+00:00

The result of flow control negotiation should not limit the next
negotiatition. If board is plugged into an old half duplex 10Mbit port,
without pause, then replugged into a gigabit port, it should negotiate
what is desired, not inherit that last negotiation.

sky2: advertising register 16 bits

2006-10-17T17:24:07+00:00

The advertising bits (from ethtool.h) fit in 16 bits.

[PATCH] sky2: revert pci express extensions

2006-10-11T08:07:45+00:00

The pci express error handling extensions don't work unless PCI access is via
mmconfig. Otherwise, all accesses to pci config registers greater than 256 fail.
Since the sky2 driver has other ways of getting to PCI config space, it works
around this short coming, but the pci_find_ext_capablity doesn't work.

This backs out commit 91aeb3edbcf4e6ed72d138ac8c22fd68e6d717c3
Go back to hardcoding, since we know where the error registers are anyway.

[PATCH] sky2: fragmented receive for large MTU

2006-09-27T21:56:31+00:00

Use hardware support for chained receive to break up large frames
into multiple pages. This avoids having to do a mult-page allocation
that can fail on a busy system due to fragmented memory.

For normal size MTU, this code behaves the same.

[PATCH] sky2: use netif_tx_lock instead of LLTX

2006-09-27T21:56:31+00:00

Use the netdevice transmit lock via netif_tx_lock rather than putting
lock in device specific code and using lockless transmit.  The code is
cleaner using netif_tx_lock, and the performance is same.
