2010-05-20wimax/i2400m: fix bad race condition check in RX pathInaky Perez-Gonzalez
The i2400m->rx_roq data structure is protected against race conditions with a reference count (i2400m->rx_roq_refcount); the pointer can be read-referenced under the i2400m->rx_lock spinlock. The code in i2400m_rx_edata() wasn't properly following access protocol, performing an invalid check on i2400m->rx_roq (which is cleared to NULL when the refcount drops to zero). As such, it was missing to detect when the data structure is no longer valid and oopsing with a NULL pointer dereference. This commit fixes said check by verifying, under the rx_lock spinlock, that i2400m->rx_roq is non-NULL and then increasing the reference count before dropping the spinlock.

We can safely assume the length is the current header size. This fixes an obscure corner case that can be triggered by non-ip packet headers or (more likely) by disabling the L2 packet recognition.

2010-05-18can: Fix SJA1000 command register writes on SMP systemsOliver Hartkopp
The SJA1000 command register is concurrently written in the rx-path to free the receive buffer _and_ in the tx-path to start the transmission. The SJA1000 data sheet, 6.4.4 COMMAND REGISTER (CMR) states: "Between two commands at least one internal clock cycle is needed in order to proceed. The internal clock is half of the external oscillator frequency." On SMP systems the current implementation leads to a write stall in the tx-path, which can be solved by adding some general locking and some time to settle the write_reg() operation for the command register. Thanks to Klaus Hitschler for the original fix and detailed problem description. This patch applies on net-2.6 and (with some offsets) on net-next-2.6 .

2010-05-17net: Add ndo_{set|get}_vf_port support for enic dynamic vnicsScott Feldman
Add enic ndo_{set|get}_vf_port ops to support setting/getting port-profile for enic dynamic devices. Enic dynamic devices are just like normal enic eth devices except dynamic enics require an extra configuration step to assign a port-profile identifier to the interface before the interface is useable. Once a port-profile is assigned, link comes up on the interface and is ready for I/O. The port-profile is used to configure the network port assigned to the interface. The network port configuration includes VLAN membership, QoS policies, and port security settings typical of a data center network. A dynamic enic initially has a zero-mac address. Before a port-profile is assigned, a valid non-zero unicast mac address should be assign to the dynamic enic interface.

The member "clock" of struct "sja1000_platform_data" is documented as "CAN bus oscillator frequency in Hz" but it's actually used as the CAN clock frequency, which is half of it. To avoid further confusion, this patch fixes it by renaming the member to "osc_freq". That way, also non mainline users will notice the change.

Based on original patch from Stanislaw Gruszka <sgruszka@redhat.com>. Using netif_carrier_off() is better than updating all the ->trans_start on all the tx queues. netif_carrier_off() needs to be called after bnx2_disable_int_sync() to guarantee no race conditions with the serdes timers that can modify the carrier state. If the chip or phy is reset, carrier will turn back on when we get the link interrupt. If there is no reset, we need to turn carrier back on in bnx2_netif_start().
