Which NIC's are capable of receiving incorrect/corrupt frames?

Hello everyone,

I am working on a project which requires me to capture packets that don't pass the CRC 32 check. I did some digging and came across ethtool utility, using which we can change ethernet device parameters.
To allow the capture of packets, which do not pass the CRC 32 I need to use the following command-
ethtool -K DEVname -rx all on.
However, for most NICs this option is fixed.
I need help finding cards that are capable of changing the -rx all option. Also How can we check if a particular card has the option non-fixed, before purchasing it as I was unable to find documentation that explicitly specify this.
Thanks in advance.
