* [SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}Arnaldo Carvalho de Melo2007-04-251-3/+4
| | | | | | | To clearly state the intent of copying to linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
* [SK_BUFF]: Convert skb->end to sk_buff_data_tArnaldo Carvalho de Melo2007-04-251-1/+1
| | | | | | | | Now to convert the last one, skb->data, that will allow many simplifications and removal of some of the offset helpers. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [SK_BUFF]: Convert skb->tail to sk_buff_data_tArnaldo Carvalho de Melo2007-04-251-1/+2
| | | | | | | | | | | | | | | So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

* [ETH]: Make eth_type_trans set skb->dev like the other *_type_transArnaldo Carvalho de Melo2007-04-251-1/+0
| | | | | | | One less thing for drivers writers to worry about. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* macb: Remove inappropriate spinlocks around mii callsHaavard Skinnemoen2007-02-171-21/+3
| | | | | | | | | | | Remove spin_lock_irqsave() around mii_ethtool_gset, mii_ethtool_sset and generic_mii_ioctl. These are unnecessary and harmful because the mii calls may call back into the mdio functions, which may sleep. Pointed out by David Brownell.

| | | | | | | | | | | | | | | | | | | | | | The obsolete SA_xxx interrupt flags have been used despite the scheduled removal. Fixup the remaining users.

| * Network: convert network devices to use struct device instead of class_deviceGreg Kroah-Hartman2007-02-071-18/+18

* | AT91: MACB supportAndrew Victor2007-02-071-2/+23
|/ | | | | | | | | | | | | | The Atmel MACB Ethernet peripheral is also integrated in the AT91SAM9260 and AT91SAM9263 processors. The differences from the AVR32 version are: * Single peripheral clock. * MII/RMII selection bit is inverted. * Clock enable bit. Original patch from Patrice Vilchez.

* [PATCH] MACB: Use __raw register accessHaavard Skinnemoen2006-12-111-1/+1
| | | | | | | | | Since macb is a chip-internal device, use __raw_readl and __raw_writel instead of readl/writel. This will perform native-endian accesses, which is the right thing to do on both AVR32 and ARM devices.

* [PATCH] MACB: Use struct delayed_work instead of struct work_structHaavard Skinnemoen2006-12-111-3/+3
| | | | | | | | | | | The macb driver calls schedule_delayed_work() and friends, so we need to use a struct delayed_work along with it.

* [PATCH] Atmel MACB ethernet driverHaavard Skinnemoen2006-12-021-0/+1210
Driver for the Atmel MACB on-chip ethernet module. Tested on AVR32/AT32AP7000/ATSTK1000. I've heard rumours that it works with AT91SAM9260 as well, and it may be possible to share some code with the at91_ether driver for AT91RM9200. Hardware documentation can be found in the AT32AP7000 data sheet, which can be downloaded from http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Changes since previous version: * Probe for PHY ID instead of depending on it being provided through platform_data. * Grab initial ethernet address from the MACB registers instead of depending on platform_data. * Set MII/RMII mode correctly. These changes are mostly about making the driver more compatible with the at91 infrastructure. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
