With portmask, we can use only upto 64 ports. This portlist option enables the user to use more than 64 ports. Now we can specify the ports in 2 different ways - Using portmask (-p [0x]nnn): mask must be in hex format - Using portlist in the following format --portlist [-p2][,p3[-p4],...] --portmask 0x2 is same as --portlist 1 --portmask 0x3 is same as --portlist 0-1 Signed-off-by: Hariprasad Govindharajan --- v6: optimized the code to check for duplicates v5: added a check to validate the ports available before setting them. also added comments in the testpmd file for the new function v4: the parser is modified so that we don't ues 2 arrays to convert the listed port values v3: squashed the 2 patches and made it 1 patch with changes only in testpmd. Also working on optmizing the parser v2: moved the parser function to testpmd --- app/test-pmd/config.c | 105 +++++++++++++++++++++++++++++++++- app/test-pmd/parameters.c | 5 ++ app/test-pmd/testpmd.h | 3 + doc/guides/testpmd_app_ug/run_app.rst | 6 ++ 4 files changed, 118 insertions(+), 1 deletion(-) diff --git a/app/test-pmd/config.c b/app/test-pmd/config.c index 9669cbd..88144d8 100644 --- a/app/test-pmd/config.c +++ b/app/test-pmd/config.c @@ -2564,7 +2564,6 @@ set_fwd_ports_list(unsigned int *portlist, unsigned int nb_pt) unsigned int i; portid_t port_id; int record_now; - record_now = 0; again: for (i = 0; i < nb_pt; i++) { @@ -2587,6 +2586,110 @@ set_fwd_ports_list(unsigned int *portlist, unsigned int nb_pt) } } +/** + * Parse and obtain the list of forwarding ports + * from the user input + * + * @param[in] list + * String containing the user input.
