Subject: [PATCH net-next 9/9] net: hns3: Fix comments for hclge_get_ring_chain_from_mbx

From: Fuyun Liang <liangfuyun1@...wei.com>

Actually, hclge_get_ring_chain_from_mbx is used to get ring type, tqp id,
and int_gl index from mailbox message. So the comments is incorrect. This
patch fixes it.

Fixes: dde1a86e93ca ("net: hns3: Add mailbox support to PF driver")
