This change corrects an issue that resulted in a null pointer dereference for the addition of VLAN 0 without any VLANs being registered. Also this code removes some unnecessary checks for defines and the unnecessary setting of VLAN flags since that is now handled within the kernel via the vlan_features.

Based on original patch/work from Jean Delvare <jdelvare@suse.de> Synchronize all IRQs when in MSI-X IRQ mode. Jean's original patch hard coded the sync with the 3 possible vectors, this patch incorporates more flexibility for the future and aligns with how igb stores the number of vectors into the adapter structure.

The pm_qos_add_request call has to register the pm_qos request with the pm_qos susbsystem before first use of the pm_qos request via pm_qos_update_request. As pm_qos changed to use plists there is no benefit in registering and unregistering the pm_qos request on ifup/ifdown and thus we move the registering into e1000_open and the unregistering in e1000_close. This fixes the following warning: [ 1.786060] WARNING: at kernel/pm_qos_params.c:264 pm_qos_update_request+0x28/0x54() [ 1.786088] Hardware name: Latitude E6500 [ 1.787045] pm_qos_update_request() called for unknown object [ 1.787966] Modules linked in: [ 1.788940] Pid: 1, comm: swapper Not tainted 2.6.35-rc5-mmotm0719 #1 [ 1.790035] Call Trace: [ 1.791121] [<ffffffff81037335>] warn_slowpath_common+0x80/0x98 [ 1.792205] [<ffffffff810373e1>] warn_slowpath_fmt+0x41/0x43 [ 1.793279] [<ffffffff81057c14>] pm_qos_update_request+0x28/0x54 [ 1.794347] [<ffffffff8134889e>] e1000_configure+0x421/0x459 [ 1.795393] [<ffffffff8134afbd>] e1000_open+0xbd/0x37c [ 1.796436] [<ffffffff8105743a>] ? raw_notifier_call_chain+0xf/0x11 [ 1.797491] [<ffffffff8145f948>] __dev_open+0xae/0xe2 [ 1.798547] [<ffffffff8145f997>] dev_open+0x1b/0x49 [ 1.799612] [<ffffffff8146e36e>] netpoll_setup+0x84/0x259 [ 1.800685] [<ffffffff81b5037c>] init_netconsole+0xbc/0x21f [ 1.801744] [<ffffffff81b5026c>] ? sir_wq_init+0x0/0x35 [ 1.802793] [<ffffffff81b502c0>] ? init_netconsole+0x0/0x21f [ 1.803845] [<ffffffff810002ff>] do_one_initcall+0x7a/0x12f [ 1.804885] [<ffffffff81b2ccae>] kernel_init+0x138/0x1c2 [ 1.805915] [<ffffffff81003554>] kernel_thread_helper+0x4/0x10 [ 1.806937] [<ffffffff81590e00>] ? restore_args+0x0/0x30 [ 1.807955] [<ffffffff81b2cb76>] ? kernel_init+0x0/0x1c2 [ 1.808958] [<ffffffff81003550>] ? kernel_thread_helper+0x0/0x10 [ 1.809958] ---[ end trace 84b562a00a60539e ]--- Signed-off-by: NFlorian Mickler <florian@mickler.org> Tested-by: NValdis Kletnieks <valdis.kletnieks@vt.edu> Tested-by: NJeff Pieper <jeffrey.e.pieper@intel.com> Signed-off-by: NJeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: NDavid S.

smp_mb() inside tg3_tx_avail() is used twice in the normal tg3_start_xmit() path (see illustration below). The full memory barrier is only necessary during race conditions with tx completion. We can speed up the tx path by replacing smp_mb() in tg3_tx_avail() with a compiler barrier. The compiler barrier is to force the compiler to fetch the tx_prod and tx_cons from memory. In the race condition between tg3_start_xmit() and tg3_tx(), we have the following situation: tg3_start_xmit() tg3_tx() if (!tg3_tx_avail()) BUG(); ... if (!tg3_tx_avail()) netif_tx_stop_queue(); update_tx_index(); smp_mb(); smp_mb(); if (tg3_tx_avail()) if (netif_tx_queue_stopped() && netif_tx_wake_queue(); tg3_tx_avail()) With smp_mb() removed from tg3_tx_avail(), we need to add smp_mb() to tg3_start_xmit() as shown above to properly order netif_tx_stop_queue() and tg3_tx_avail() to check the ring index. If it is not strictly ordered, the tx queue can be stopped forever. This improves performance by about 3% with 2 ports running bi-directional 64-byte packets.
