cb161940c2
Adds support for timestamping received UDP packets, either in hardware or in kernel. Builds on the existing support of SO_TIMESTAMP for SocketCAN. Implementation uses CLOCK_REALTIME for timestamping to match the behavior of Linux. This could be made configurable in future if needed.

int "Preallocated socket callbacks"

---help---
|
|
Number of preallocated socket callbacks (all tasks).
|
|
|
|
This number of callbacks will be pre-allocated during system boot.
|
|
If dynamic callbacks allocation is enabled, more callbacks may be
|
|
allocated at a later time, as the system needs them. Else this
|
|
will be the maximum number of callbacks available to the system
|
|
at all times.
|
|
|
|
Set to 0 to disable (and rely only on dynamic allocations).
|
|
|
|
config NET_ALLOC_DEVIF_CALLBACKS
|
|
int "Dynamic socket callbacks allocation"
|
|
default 0
|
|
---help---
|
|
Dynamic memory allocations for socket callbacks.
|
|
|
|
When set to 0 all dynamic allocations are disabled.
|
|
|
|
When set to 1 a new callback will be allocated every time, and
|
|
it will be free'd when no longer needed.
|
|
|
|
Setting this to 2 or more will allocate the callbacks in batches
|
|
(with batch size equal to this config). When a callback is no
|
|
longer needed, it will be returned to the free callbacks pool,
|
|
and it will never be deallocated!
