Name
dev_alloc_skb -- allocate an skbuff for sending
Synopsis
struct sk_buff * dev_alloc_skb (unsigned int length);
Arguments
- length
length to allocate
Description
Allocate a new &sk_buff and assign it a usage count of one. The
buffer has unspecified headroom built in. Users should allocate
the headroom they think they need without accounting for the
built in space. The built in space is used for optimisations.
NULL is returned in there is no free memory. Although this function
allocates memory it can be called from an interrupt.
