[dpdk-stable] [PATCH v1] net/dpaa2: fixes issue of accidentally resetting rx offloads flags

[Sachin Saxena]

The JUMBO frame handling in dpaa2_dev_mtu_set api was not correct.
When frame_size is greater than RTE_ETHER_MAX_LEN, the
intention is to add JUMBO flag in rx offload while it was resetting
all other flags other than JUMBO as AND operator was used instead of OR.

Hi,
About the title of this patch:
- "fixes" should be "fix" (infinitive verb)
- "issue" is not needed after "fix"
- we don't care whether it is "accidentally resetting"
You should just tell what is fixed and what is the case:
	fix Rx offload flags on jumbo MTU set

[Sachin Saxena] Thanks for information. I got your point.

[dpdk-stable] [PATCH v2] net/dpaa2: fix Rx offload flags on jumbo MTU set

[Sachin Saxena]

The JUMBO frame handling in dpaa2_dev_mtu_set api was not correct.
When frame_size is greater than RTE_ETHER_MAX_LEN, the
intention is to add JUMBO flag in rx offload while it was resetting
all other flags other than JUMBO as AND operator was used instead of OR.
