mac_address not being configured by ios_l3_interfaces #1220
Description
SUMMARY
I have configured mac_address for an L3 interface. The module shows it being parsed as a module_arg, but the mac address is not rendered as a config change, nor sent to the device.

STEPS TO REPRODUCE
Configure the "mac_address" module param for an interface. I am including IP addresses to confirm that module is generating at least some configuration for the interface (it does).
- name: "Test L3 mac_address"
cisco.ios.ios_l3_interfaces:
state: "rendered"
config:
- name: "Vlan101"
mac_address: "dead.beef.f00d"
ipv6:
- address: "2001:db8::1/64"
ipv4:
- address: "203.0.113.1/24"EXPECTED RESULTS
Expecting "rendered" command output to include "mac-address dead.beef.f00d", e.g.:
"rendered": [
"interface Vlan101",
"mac-address dead.beef.f00d",
"ip address 203.0.113.1 255.255.255.0",
"ipv6 address 2001:db8::1/64"
]
ACTUAL RESULTS
Other configuration items are rendered, but not "mac-address". Verbose outputs show that the param is being read by the module.

]
}
When applied to a device (not rendered), output is the same; no 'mac-address' config command is sent to the device.
Changed state does not vary, regardless of whether mac-address is present on the configured device. So perhaps it's not being checked when querying the device?
