2007-10-10[NET]: Introduce and use print_mac() and DECLARE_MAC_BUF()Joe Perches

2007-10-10[NET]: Nuke SET_MODULE_OWNER macro.Ralf Baechle
It's been a useless no-op for long enough in 2.6 so I figured it's time to remove it. The number of people that could object because they're maintaining unified 2.4 and 2.6 drivers is probably rather small.

2007-10-10[NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger
Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted. Integrated Stephen's follow-on kerneldoc additions, and restored poll_list handling to the old style to fix mutual exclusion issues. -DaveM ] Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S.

2007-04-25[SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}Arnaldo Carvalho de Melo
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>
2007-04-25[SK_BUFF]: Convert skb->end to sk_buff_data_tArnaldo Carvalho de Melo
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>
2007-04-25[SK_BUFF]: Convert skb->tail to sk_buff_data_tArnaldo Carvalho de Melo
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.

2007-02-17macb: Remove inappropriate spinlocks around mii callsHaavard Skinnemoen
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 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.

2006-12-11[PATCH] MACB: Use __raw register accessHaavard Skinnemoen
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.

2006-12-11[PATCH] MACB: Use struct delayed_work instead of struct work_structHaavard Skinnemoen
The macb driver calls schedule_delayed_work() and friends, so we need to use a struct delayed_work along with it.

2006-12-02[PATCH] Atmel MACB ethernet driverHaavard Skinnemoen
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>
