* ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny2011-04-291-4/+7
| | | | | | | | | | | | | | | | | | | | This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated.

* vlan: Don't check for vlan group before vlan_tx_tag_present.Jesse Gross2010-10-211-1/+1
| | | | | | | | | | | | | Many (but not all) drivers check to see whether there is a vlan group configured before using a tag stored in the skb. There's not much point in this check since it just throws away data that should only be present in the expected circumstances. However, it will soon be legal and expected to get a vlan tag when no vlan group is configured, so remove this check from all drivers to avoid dropping the tags.

| * via-velocity: Fix races on shared interruptsSimon Kagstrom2010-02-101-11/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes two potential races in the velocity driver: * Move the ACK and error handler to the interrupt handler. This fixes a potential race with shared interrupts when the other device interrupts before the NAPI poll handler has finished. As the velocity driver hasn't acked it's own interrupt, it will then steal the interrupt from the other device. * Use spin_lock_irqsave in velocity_poll. In the current code, the interrupt handler will deadlock if e.g., the NAPI poll handler is executing when an interrupt (for another device) comes in since it tries to take the already held lock. Also unlock the spinlock only after enabling the interrupt in velocity_poll. The error path is moved to the interrupt handler since this is where the ISR is checked now.

| * via-velocity: Give RX descriptors to the NIC later on open or MTU changeBen Hutchings2010-01-031-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | velocity_open() calls velocity_give_many_rx_descs(), which gives RX descriptors to the NIC, before installing an interrupt handler or calling velocity_init_registers(). I think this is very unsafe and it appears to explain the bug report <http://bugs.debian.org/508527>. On MTU change, velocity_give_many_rx_descs() is again called before velocity_init_registers(). I'm not sure whether this is unsafe but it does look wrong. Therefore, move the calls to velocity_give_many_rx_descs() after request_irq() and velocity_init_registers().
