From: Ravi Kerur @ 2017-03-04 20:44 UTC (permalink / raw)
To: dev; +Cc: konstantin.ananyev, bruce.richardson, Ravi Kerur
v3:
> Fix additional checkpatch coding style issues.
v2:
> Fix checkpatch errors and warnings related to non strings
greater than 80 characters.
> MACRO GET_CB_FIELD and strings greater than 80 characters
warnings are not fixed.
v1:
l3fwd-acl changes:
> Merge common init code in l3fwd-acl and l3fwd into
main.c.
> Move non-critical inline functions to l3fwd_acl.h.
> Move critial packet processing inline functions to
l3fwd_acl_scalar.h
> Move l3fwd-acl init code to l3fwd_acl.c.
> Delete l3fwd-acl directory.
l3fwd changes:
> Add '-A' as an option for ACL processing.
> Merge parsing options from l3fwd-acl and l3fwd. Retain
l3fwd-acl definitions.
> Move specific setup functions (setup_acl, setup_lpm
and setup_hash).
Testing:
> Compiled successfully for x86_64-native-linuxapp-gcc
> Tested LPM, EM and ACL basic functionality.

v3:
> Fix additional checkpatch coding style issues.
v2:
> Fix checkpatch warnings.
v1:
> Remove static array configuration of Dest IP,Src IP, Dest
port, Src port, Proto and IF_OUT for EM and EM6 config.
> Add reading configuration from a file.
> Format of configuration file is as follows
#EM route entries,
#Dest-IP Src-IP Dest-port Src-port Proto IF_OUT
