In case a Rx packet received is more than the MTU configured, then the packet appears in the ring with LD bit set which further gets processed even if the buffers length allocated is less than the received packet len. The frame hence consumes more than 1 rx desc and kfree for an skb with no LD bit set and neither error bits set got called causing kernel panic. Fix: Drops such pkts for which the configured MTU and received pkt len is different to avoid packects consuming more than 1 rx desc, and always accommodate single packet in single rx desc buffer.
