-* Rules to follow when using local atomic operations
-
-- Variables touched by local ops must be per cpu variables.
-- _Only_ the CPU owner of these variables must write to them.
-- This CPU can use local ops from any context (process, irq, softirq, nmi, ...)
- to update its local_t variables.
-- Preemption (or interrupts) must be disabled when using local ops in
- process context to make sure the process won't be migrated to a
- different CPU between getting the per-cpu variable and doing the
- actual local op.
-- When using local ops in interrupt context, no special care must be
- taken on a mainline kernel, since they will run on the local CPU with
- preemption already disabled. I suggest, however, to explicitly
- disable preemption anyway to make sure it will still work correctly on
- -rt kernels.
-- Reading the local cpu variable will provide the current copy of the
- variable.
-- Reads of these variables can be done from any CPU, because updates to
- "long", aligned, variables are always atomic. Since no memory
- synchronization is done by the writer CPU, an outdated copy of the
- variable can be read when reading some _other_ cpu's variables.

2) Do not forget to update netdev->trans_start to jiffies after
each new tx packet is given to the hardware.
-3) Do not forget that once you return 0 from your hard_start_xmit
+3) A hard_start_xmit method must not modify the shared parts of a
+ cloned SKB.
+
+4) Do not forget that once you return 0 from your hard_start_xmit
method, it is your driver's responsibility to free up the SKB
and in some finite amount of time.
A more advanced driver could for example check that a HTTP server is
still responding before doing the write call to ping the watchdog.
-When the device is closed, the watchdog is disabled. This is not
-always such a good idea, since if there is a bug in the watchdog
-daemon and it crashes the system will not reboot. Because of this,
-some of the drivers support the configuration option "Disable watchdog
-shutdown on close", CONFIG_WATCHDOG_NOWAYOUT. If it is set to Y when
-compiling the kernel, there is no way of disabling the watchdog once
-it has been started. So, if the watchdog daemon crashes, the system
-will reboot after the timeout has passed. Watchdog devices also usually
-support the nowayout module parameter so that this option can be controlled
-at runtime.
-
-Drivers will not disable the watchdog, unless a specific magic character 'V'
-has been sent /dev/watchdog just before closing the file. If the userspace
-daemon closes the file without sending this special character, the driver
-will assume that the daemon (and userspace in general) died, and will stop
-pinging the watchdog without disabling it first. This will then cause a
-reboot if the watchdog is not re-opened in sufficient time.
