## NAME

pskb\_put - add data to the tail of a potentially fragmented buffer

## ARGUMENTS

*skb*

start of the buffer to use

*tail*

tail fragment of the buffer to use

*len*

This function extends the used data area of the potentially fragmented buffer. *tail* must be the last fragment of *skb* -- or *skb* itself. If this would exceed the total buffer size the kernel will panic. A pointer to the first byte of the extra data is returned.
