Intel IAVF base driver structure definition is wrong

Intel IAVF base driver structure definition is wrong

[Morten Brørup]

Hi Vladimir,

This build failure seems to be caused by a bug in the IAVF base driver:
https://github.com/ovsrobot/dpdk/actions/runs/25104438552/job/73561907869#step:19:803

struct virtchnl_rss_key {
	u16 vsi_id;
	u16 key_len;
	u8 key[1];         /* RSS hash key, packed bytes */
};

The "key[1]" should be "key[]".
And when copying to it, remember to change "sizeof(struct virtchnl_rss_key) - 1" to "sizeof(struct virtchnl_rss_key)".

Other Intel drivers may have the same bug.


Venlig hilsen / Kind regards,
-Morten Brørup
