Srinivasan <kys@xxxxxxxxxxxxx> We have generic infrastructure to do this, please try instead: err = skb_cow_head(skb, pkt_sz); this will take care of everything for you and you can get rid of all of this dynamic memory allocation etc. in this code path. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
