dec3840 & ice_ddp_load

[Kets_One]

Hi all, question about the default configuration of the dec3840 as downloadable from https://docs.opnsense.org/hardware/defaults.html.

I noticed that there is a tunable there i can't explain:
...
  <sysctl>
    <item>
      <tunable>ice_ddp_load</tunable>
      <value>YES</value>
      <descr>Include DDP package file for Intel ice driver</descr>
    </item>
  </sysctl>

Two questions come up in my head:
1. Why is his tunable in the default config for the dec3840? As far as i know this intended to the intel E810 NICs only.
I have intel i210 NICs. Is this tunable required for proper operation?

2. On the forums another (related?) tunable is mentioned often in conjunction with the former:  if_ice_load="YES".
Why is this not included in the default config?

PS: I've tried to add the ice_ddp_load tunable earlier, but caused instability/boot failure if i can recall correctly.
