Subject: [dpdk-dev] [RFC] Clang errors with bit fields and setting value of ~0.
Date: Sat, 29 Nov 2014 10:33:36 -0600	[thread overview]
Message-ID: <1417278816-24011-1-git-send-email-keith.wiles@windriver.com> (raw)

error: implicit truncation from 'int' to bitfield
      changes value from -1 to 127 [-Werror,-Wbitfield-constant-conversion]
                        tx_offload_mask.l2_len = ~0;
Converted to use correct bit values
						tx_offload_mask.l2_len = 0x7f;
