Once packet received by MAC - 4-tuples will be extracted
from the packet and given to RSS hash engine. Hash function
will generate hash value by using 40byte key.
From hash value LSB bits used as index to RSS lookup table to
find out DMA channel number. If there is a match - packet is
routed to corresponding DMA channel. If there is no match -
packet will be dropped and error will be returned in receive desc.

Issue:
- Current values for checksum flags are too
generic for QNX requirements.

Fix:
- Add specific flags for TCP/UDP, IP v4/v6
- Update value for OSI_CHECKSUM_UNNECESSARY
  to use it as a flag instead of value.

acbb40e98f nvethernetrm: drop rx packets longer than current MTU 
Issue: When JE is set, HW will accept any valid packet on Rx
upto 9K or 16K (depending on GPSCLE bit), irrespective of
whether MTU set is lower than these specific values. When
Rx buf len is allocated to be exactly same as MTU, HW will
consume more than 1 Rx desc to place the larger packet.

Fix: Drop Rx packets which are longer than currently set
MTU since HW cannot drop them.

68a6f0cb46 osi: dma: Add flags for rx checksum. 
Issue:
- Current values for checksum flags are too
generic for QNX requirements.

Fix:
- Add specific flags for TCP/UDP, IP v4/v6
- Update value for OSI_CHECKSUM_UNNECESSARY
  to use it as a flag instead of value.

46c199bcae nvethernetrm: drop rx packets longer than current MTU 
Issue: When JE is set, HW will accept any valid packet on Rx
upto 9K or 16K (depending on GPSCLE bit), irrespective of
whether MTU set is lower than these specific values. When
Rx buf len is allocated to be exactly same as MTU, HW will
consume more than 1 Rx desc to place the larger packet.

Fix: Drop Rx packets which are longer than currently set
MTU since HW cannot drop them.
