2017-07-14Introduce l{2,3,4}_hdr_offset fields in the buffer metadataDamjan Marion1-2/+2
To save space in the first cacheline following is changed: - total_length_not_including_first_buffer moved to the 2nd cacheline. This field is used only when VLIB_BUFFER_TOTAL_LENGTH_VALID and VLIB_BUFFER_NEXT_PRESENT are both set. - free_list_index is now stored in 4bits inside flags, which allows up to 16 free lists. In case we need more we can store index in the 2nd cachelin Change-Id: Ic8521350819391af470d31d3fa1013e67ecb7681 Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-02-02BFD: SHA1 authenticationKlement Sekera1-57/+286
Add authentication support to BFD feature. Out of three existing authentication types, implement SHA1 (sole RFC requirement). Simple password is insecure and MD5 is discouraged by the RFC, so ignore those. Add/change APIs to allow configuring BFD authentication keys and their usage with BFD sessions.
