Hi,
while this approach to merging the values from two sources (config
struct and cmdline) works, I'm not sure it's the best way to implement
this. I would have thought it more logical to separate out cmdline args
into name-value pairs to add to the cfgfile struct internally instead.
However, this has the disadvantage of forcing a dependency on cfgfile,
or adding a third name-value pair struct to DPDK [after kvargs, which
supports flat pairs, and cfgfile, which supports sections and pairs].
Using the cfgfile struct also saves us from "flattening out"
hierarchical information we may wish to add in the config file. For
example, consider the following cfgfile structure:
[DPDK]
lcores = 20-25
socket-mem = 2048, 1024
vdevs = 2
[DPDK.vdev0]
name = eth_pcap0
rx_pcap = /path/to/file
tx_pcap = /path/to/other_file
[DPDK.vdev1]
name = eth_tap0
iface = iface_arg
Longer term, it would be good to keep those vdev entries separated as passed
as such to the driver, rather than merging them back into a single
string to be separated out again by kvargs lib.
