[ Upstream commit 2075bf150ddf320df02c05e242774dc0f73be1a1 ]
During the initial design, the IPv4 ip_flag mask was set to 0xff. Which results to filter only fragmets with (fragment_offset == 0). As part of the fix, updated the mask to 0x20 to filter all the fragmented packets irrespective of the fragment_offset value.
