GROPackets is the number of held packets. Those are candidate packets held by the kernel to

be processed individually or to be merged to larger packets. This number is usually zero.

GROMerged is the number of packets that merged to larger packets. Usually this number

increases if there is any continuous traffic stream present.

ethtool can also be used to switch off the GRO/LRO options when necessary:

[root@host]# ethtool -K eth6 gro off

[root@host]# ethtool -k eth6

Offload parameters for eth6:

rx-checksumming: on

tx-checksumming: on

scatter-gather: on

tcp-segmentation-offload: on

udp-fragmentation-offload: off

generic-segmentation-offload: on

generic-receive-offload: off

large-receive-offload: off

The output above shows a disabled GRO.
