    igb: set max size RX buffer when store bad packet is enabled

    JIRA: https://issues.redhat.com/browse/RHEL-15181

    CVE: CVE-2023-45871

    commit bb5ed01cd2428cd25b1c88a3a9cba87055eb289f

    Author: Radoslaw Tyl <radoslawx.tyl@intel.com>

    Date:   Thu Aug 24 13:46:19 2023 -0700

        igb: set max size RX buffer when store bad packet is enabled

        Increase the RX buffer size to 3K when the SBP bit is on. The size of

        the RX buffer determines the number of pages allocated which may not

        be sufficient for receive frames larger than the set MTU size.
