2007-02-05sky2: handle network device allocation failureshemminger@linux-foundation.org
If alloc_etherdev() failed, then sky2_init_netdev will return NULL, and sky2_probe would end up returning 0 instead of -ENOMEM. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-02-05forcedeth: tx limitingAyaz Abdulla
This patch optimizes the logic for tx limiting. It adds a flag to check on the completion side instead of recalculating the number of empty slots.

This patch breaks up the routines into two versions, one for legacy descriptor versions (ver 1 and ver 2) and one for desc ver 3.

2007-02-05bonding: update versionJay Vosburgh
Update version number to reflect recent changes. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-02-05bonding: modify sysfs support to permit multiple loadsJay Vosburgh
The existing code would blindly attempt to create the bonding_masters file (in /sys/class/net) every time the module was loaded. When the module is loaded multiple times (which is the historical method used by initscripts and sysconfig to create multiple bonding interfaces), this caused load failure of the second module load attempt, as the creation request would fail. This changes the code to note the failure, arrange to not remove the bonding_masters file upon module exit, and then return success. Bonding interfaces created by the second or subsequent loads of the module will not exist in bonding_masters. This is not a significant change, as previously only the interfaces from the most recent load of the module would be listed. Both situations are less than optimal, but this case permits compatibility with existing distro configuration scripts, and is consistent. Note that previously, the sysfs create request would overwrite the exsting bonding_masters file and succeed, allowing multiple loads of the module. The sysfs code has recently changed to return an error if the file being created already exists. Patrick McHardy <kaber@trash.net>, who reported this problem, observed crashes on the old kernel (before sysfs checked for duplicates). I did not experience such crashes, but this change should resolve them. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-02-05bonding: fix error check in sysfs creationJay Vosburgh
The existing code did not correctly handle failures to create the per-interface sysfs group for bonding. Modified code to notice errors, and correctly unwind. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-02-05bonding: fix device name allocation errorJay Vosburgh
The code to select names for the bonding interfaces was, for the non-sysfs creation case, always using a hard-coded set of bond0, bond1, etc, up to max_bonds. This caused conflicts for the second or subsequent loads of the module. Changed the code to obtain device names from dev_alloc_name().

2007-02-05bonding.h: "extern inline" -> "static inline"Adrian Bunk
"extern inline" generates a warning with -Wmissing-prototypes and I'm currently working on getting the kernel cleaned up for adding this to the CFLAGS since it will help us to avoid a nasty class of runtime errors. If there are places that really need a forced inline, __always_inline would be the correct solution. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Jeff Garzik <jeff@garzik.org>

The OAKNET driver: - has been marked as BROKEN for more than two years and - is still marked as BROKEN. Drivers that had been marked as BROKEN for such a long time seem to be unlikely to be revived in the forseeable future.

2007-02-05driver for Silan SC92031 netdevCesar Eduardo Barros
This is a driver for the Silan SC92031/Rsltek 8139D NIC chip. This chip is found on at least one counterfeit Encore ENL832-TX-RENT NIC [1], which came with a mini-CD with the 2.4 driver. A slightly older version of the driver was found at [2]. The main difference between them is that the newer one has a small bugfix in the RX path, a lot of gratuitous renaming of functions, all the printable strings changed to show as a "Rsltek 8139D" [sic], and a PCI ID of 8139 instead of 2031. The driver on this patch is a rewrite of the vendor drivers (based mostly on the older one). Changes from the previous patch sent to netdev: - Use MMIO instead of PIO - Changed TX bounce buffers allocation - Use skb_copy_and_csum_dev - Several small bug fixes - Tested for more than just a few minutes each time [1] See http://www.encore-usa.com/faq.php under ENL832-TX-RENT for more information [2] Look for SL_LINUX.ZIP (which is really a .tar.gz) at http://broadbandforum.in/dataone_Intex_LAN_cardlinux-t4207-s15.html [3] To compile on 2.6.17, simply add back the last argument to the interrupt handler in two places, and copy the boolean declarations from 2.6.19 [akpm@osdl.org: build fixes] Signed-off-by: Cesar Eduardo Barros <cesarb@cesarb.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
