Adds validations in OvsGetIp() to make sure the IHL is
within valid bounds. If IHL is invalid, then the packet
is dropped by the callers of this function.

*Added OvsExtractLayers - populates only the layers field without unnecessary
memory operations for flow part
*If in STT header the flags are 0 then force packets checksums calculation
on receive.
*Ensure correct pseudo checksum is set for LSO both on send and receive.
Linux includes the segment length to TCP pseudo-checksum conforming to
RFC 793 but in case of LSO Windows expects this to be only on
Source IP Address, Destination IP Address, and Protocol.
*Fragment expiration on rx side of STT was set to 30 seconds, but the correct
timeout would be TTL of the packet

This reverts commit a26b2023ce33fed1ef962012dc2c03765d2e92cb.
This patch punishes performance without the implementation of
megaflows on Windows.
Once megaflows is implemented in the flow logic this patch will be
revisited.
