Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

vlan: Precise RX stats accounting With multi queue devices, its possible that several cpus call vlan RX routines simultaneously for the same vlan device. We update RX stats counter without any locking, so we can get slightly wrong counters. One possible fix is to use percpu counters, to get precise accounting and also get guarantee of no cache line ping pongs between cpus.

vlan: uninline __vlan_hwaccel_rx The function is huge and included at least once in every VLAN acceleration capable driver. Uninline it; to avoid having drivers depend on the VLAN module, the function is always built in statically when VLAN is enabled. With all VLAN acceleration capable drivers that build on x86_64 enabled, this results in: text data bss dec hex filename 6515227 854044 343968 7713239 75b1d7 vmlinux.inlined 6505637 854044 343968 7703649 758c61 vmlinux.uninlined ---------------------------------------------------------- -9590 Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

vlan: Add GVRP support Add GVRP support for dynamically registering VLANs with switches. By default GVRP is disabled because we only support the applicant-only participant model, which means it should not be enabled on vlans that are members of a bridge. Since there is currently no way to cleanly determine that, the user is responsible for enabling it. The code is pretty small and low impact, its wrapped in a config option though because it depends on the GARP implementation and the STP core.

vlan: propogate ethtool speed values This enables more ethtool information. The speed and settings of the underlying device are propagated up. This makes services like SNMP that use ethtool to get speed setting, work when managing a vlan, without adding silly heurtistics into SNMP daemon. For the driver info, just use existing driver strings. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

[VLAN]: Proc entry is not renamed when vlan device name changes. This may lead to situations, when each of two proc entries produce data for the other's device. Looks like a BUG, so this patch is for net-2.6. It will not apply to net-2.6.26 since dev->nd_net access is replaced with dev_net(dev) one.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
