Perform segmentation on skb.

## NAME

\_\_skb\_gso\_segment - Perform segmentation on skb.

## SYNOPSIS

**struct sk\_buff \* \_\_skb\_gso\_segment(struct sk\_buff \*** *skb***, netdev\_features\_t** *features***, bool** *tx\_path***);**

## ARGUMENTS

*skb*

buffer to segment

*features*

features for the output path (see dev-\>features)

*tx\_path*
