2010-11-28ethoc: rework interrupt handlingJonas Bonn1-27/+49
The old interrupt handling was incorrect in that it did not account for the fact that the interrupt source bits get set irregardless of whether or not their corresponding mask is set. This patch fixes that by masking off the source bits for masked interrupts. Furthermore, the handling of transmission events is moved to the NAPI polling handler alongside the reception handler, thus preventing a whole bunch of interrupts during heavy traffic.

2010-11-28ethoc: Double check pending RX packetJonas Bonn1-2/+13
An interrupt may occur between checking bd.stat and clearing the interrupt source register which would result in the packet going totally unnoticed as the interrupt will be missed. Double check bd.stat after clearing the interrupt source register to guard against such an occurrence. Signed-off-by: Jonas Bonn <jonas@southpole.se> Signed-off-by: David S.

2010-11-28ethoc: enable interrupts after napi_completeAdam Edvardsson1-1/+1
Occasionally, it seems that some race is causing the interrupts to not be reenabled otherwise with the end result that networking just stops working.

2010-11-28ethoc: Add device tree configurationJonas Bonn1-2/+30
This patch adds the ability to describe ethernet devices via a flattened device tree. As device tree remains an optional feature, these bits all need to be guarded by CONFIG_OF ifdefs. MAC address is settable via the device tree parameter "local-mac-address"; however, the selection of the phy id is limited to probing, for now.

2010-11-28netxen: avoid using reset_devices as it may become obsoleteRajesh Borundia1-2/+4
In kdump environment do not depend on reset_devices parameter to reset the device as the parameter may become obsolete. Instead use an adapter specific mechanism to determine if the device needs a reset. Driver maintains a count of number of pci functions probed and decrements the count when remove handler of that pci function is called. If the first probe, probe of function 0, detects the count as non zero then reset the device.

2010-11-22macvlan: Introduce 'passthru' mode to takeover the underlying deviceSridhar Samudrala1-1/+32
With the current default 'vepa' mode, a KVM guest using virtio with macvtap backend has the following limitations. - cannot change/add a mac address on the guest virtio-net - cannot create a vlan device on the guest virtio-net - cannot enable promiscuous mode on guest virtio-net To address these limitations, this patch introduces a new mode called 'passthru' when creating a macvlan device which allows takeover of the underlying device and passing it to a guest using virtio with macvtap backend. Only one macvlan device is allowed in passthru mode and it inherits the mac address from the underlying device and sets it in promiscuous mode to receive and forward all the packets.

2010-11-19filter: optimize sk_run_filterEric Dumazet1-8/+4
Remove pc variable to avoid arithmetic to compute fentry at each filter instruction. Jumps directly manipulate fentry pointer. As the last instruction of filter[] is guaranteed to be a RETURN, and all jumps are before the last instruction, we dont need to check filter bounds (number of instructions in filter array) at each iteration, so we remove it from sk_run_filter() params. On x86_32 remove f_k var introduced in commit 57fe93b374a6b871 (filter: make sure filters dont read uninitialized memory) Note : We could use a CONFIG_ARCH_HAS_{FEW|MANY}_REGISTERS in order to avoid too many ifdefs in this code. This helps compiler to use cpu registers to hold fentry and A accumulator. On x86_32, this saves 401 bytes, and more important, sk_run_filter() runs much faster because less register pressure (One less conditional branch per BPF instruction) # size net/core/filter.o net/core/filter_pre.o text data bss dec hex filename 2948 0 0 2948 b84 net/core/filter.o 3349 0 0 3349 d15 net/core/filter_pre.o on x86_64 : # size net/core/filter.o net/core/filter_pre.o text data bss dec hex filename 5173 0 0 5173 1435 net/core/filter.o 5224 0 0 5224 1468 net/core/filter_pre.o Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: David S.
