From: Olivier Matz Date: Wed, 26 Nov 2014 15:04:48 +0000 (+0100) Subject: mbuf: get the name of offload flags X-Git-Tag: spdx-start~10063 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e4a1c50e69f86944cb49384eb3211d080cb44f7a;p=dpdk.git mbuf: get the name of offload flags In test-pmd (rxonly.c), the code is able to dump the list of ol_flags. The issue is that the list of flags in the application has to be synchronized with the flags defined in rte_mbuf.h. This patch introduces 2 new functions rte_get_rx_ol_flag_name() and rte_get_tx_ol_flag_name() that returns the name of a flag from its mask. It also fixes rxonly.c to use this new functions and to display the proper flags.
