net/ice: add devargs for disabling mac filter
Checks
Commit Message
From: "ke1x.zhang" <ke1x.zhang@intel.com>
This patch adds support to disable mac filter which will
be used by ice driver when setting dpdk_devargs config
field in the TRex config file.
Mac filter is not disabled in default.

Why use 4 bytes for a flag when a single bit would do.
Hi Stephen:
Thanks for your comments.
I just follow the definition of other variables like pipe_mode_support, safe_mode_support.
And when I run the testpmd , I could write the command like this:
./dpdk-testpmd -l 16-32 -a ca:00.0,mac-filter-disable=1 -a ca:00.1 -- -i
The value could 1 or 0.
Would you please give me some guidance about the definition of the variable?

After modifying the code like this:
struct ice_devargs {
int rx_low_latency : 1;
int safe_mode_support : 1;
int pipe_mode_support : 1;
int mac_filter_disable : 1;
I met a issue when compiling the code:
../drivers/net/ice/ice_ethdev.c:2076:19: error: cannot take address of bit-field 'safe_mode_support'
2076 | &parse_bool, &ad->devargs.safe_mode_support);
| ^
../drivers/net/ice/ice_ethdev.c:2081:19: error: cannot take address of bit-field 'pipe_mode_support'
2081 | &parse_bool, &ad->devargs.pipe_mode_support);
| ^
../drivers/net/ice/ice_ethdev.c:2086:18: error: cannot take address of bit-field 'mac_filter_disable'
2086 | &parse_bool, &ad->devargs.mac_filter_disable);
| ^
../drivers/net/ice/ice_ethdev.c:2101:19: error: cannot take address of bit-field 'rx_low_latency'
2101 | &parse_bool, &ad->devargs.rx_low_latency);
It seems that bitfields members aren't addressable.

Would a uint8_t work? Also parse_bool might make assumptions about size.
