Since commit d25f06ea466e "vmxnet3: fix netpoll race condition", the vmxnet3 driver fails to build when CONFIG_PCI_MSI is disabled, because it unconditionally references the vmxnet3_msix_rx() function.

2014-03-11vmxnet3: fix netpoll race conditionNeil Horman
vmxnet3's netpoll driver is incorrectly coded. It directly calls vmxnet3_do_poll, which is the driver internal napi poll routine. As the netpoll controller method doesn't block real napi polls in any way, there is a potential for race conditions in which the netpoll controller method and the napi poll method run concurrently. The result is data corruption causing panics such as this one recently observed: PID: 1371 TASK: ffff88023762caa0 CPU: 1 COMMAND: "rs:main Q:Reg" #0 [ffff88023abd5780] machine_kexec at ffffffff81038f3b #1 [ffff88023abd57e0] crash_kexec at ffffffff810c5d92 #2 [ffff88023abd58b0] oops_end at ffffffff8152b570 #3 [ffff88023abd58e0] die at ffffffff81010e0b #4 [ffff88023abd5910] do_trap at ffffffff8152add4 #5 [ffff88023abd5970] do_invalid_op at ffffffff8100cf95 #6 [ffff88023abd5a10] invalid_op at ffffffff8100bf9b [exception RIP: vmxnet3_rq_rx_complete+1968] RIP: ffffffffa00f1e80 RSP: ffff88023abd5ac8 RFLAGS: 00010086 RAX: 0000000000000000 RBX: ffff88023b5dcee0 RCX: 00000000000000c0 RDX: 0000000000000000 RSI: 00000000000005f2 RDI: ffff88023b5dcee0 RBP: ffff88023abd5b48 R8: 0000000000000000 R9: ffff88023a3b6048 R10: 0000000000000000 R11: 0000000000000002 R12: ffff8802398d4cd8 R13: ffff88023af35140 R14: ffff88023b60c890 R15: 0000000000000000 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 #7 [ffff88023abd5b50] vmxnet3_do_poll at ffffffffa00f204a [vmxnet3] #8 [ffff88023abd5b80] vmxnet3_netpoll at ffffffffa00f209c [vmxnet3] #9 [ffff88023abd5ba0] netpoll_poll_dev at ffffffff81472bb7 The fix is to do as other drivers do, and have the poll controller call the top half interrupt handler, which schedules a napi poll properly to recieve frames Tested by myself, successfully.

2013-02-25vmxnet3: fix ethtool ring buffer size settingNeil Horman
Noticed that vmxnet3's get_ringparam function was returning the summation of all ring buffers on a NIC, rather than just the size of any one ring. This causes problems when a vmxnet3 instance has multiple queues, as ethtool, when setting ring parameters, first gets the current ring parameters to set the existing values in the set_ringparm commannd. The result is, that unless both rx and tx ring sizes are set in a single operation, which ever ring is not set will silently have its ring count multiplied by the number of queues on the NIC until it reaches a driver defined maxiumum value. Fix it by not multiplying the rx and tx ring sizes by the number of queues in the system, like every other driver. Tested by myself successfully.

2013-01-29vmxnet3: set carrier state properly on probeNeil Horman
vmxnet3 fails to set netif_carrier_off on probe, meaning that when an interface is opened the __LINK_STATE_NOCARRIER bit is already cleared, and so /sys/class/net/<ifname>/operstate remains in the unknown state. Correct this by setting netif_carrier_off on probe, like other drivers do. Also, while we're at it, lets remove the netif_carrier_ok checks from the link_state_update function, as that check is atomically contained within the netif_carrier_[on|off] functions anyway Tested successfully by myself Signed-off-by: Neil Horman <nhorman@tuxdriver.com> CC: "David S.

2013-01-16vmxnet3: use netdev_dbgStephen Hemminger
Use netdev_dbg() rather than dev_dbg() because the former prints the device name which is more useful than the pci name. Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-01-16vmxnet3: fix messages printed before registrationStephen Hemminger
This messages that occur during boot time from this device when netdev_err is called before calling register_netdevice(). Switch to using dev_XXX macros which correlate message with PCI info which is available. Rather than fixing the features message, just remove it since the information is redundant and available through ethtool.

2012-11-03vmxnet3: must split too big fragmentsEric Dumazet
vmxnet3 has a 16Kbytes limit per tx descriptor, that happened to work as long as we provided PAGE_SIZE fragments. Our stack can now build larger fragments, so we need to split them to the 16kbytes boundary.

2012-06-06drivers: net: Remove casts to same typeJoe Perches
Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.
