[via GitHub]

CV-Bowen opened a new pull request, #11485:
URL: https://github.com/apache/nuttx/pull/11485

   ## Summary
   The length of some config elements are not equal to 1,2,4,8, so we can't 
assert in virtio_mmio_config_read/write() direclty when length != 1,2,4,8
   
   For example, in virtio_net_config from virtio spec v1.2 struct 
virtio_net_config {
        u8 mac[6];
        le16 status;
        le16 max_virtqueue_pairs;
        le16 mtu;
        le32 speed;
        u8 duplex;
        u8 rss_max_key_size;
        le16 rss_max_indirection_table_length;
        le32 supported_hash_types;
   };
   
   The mac length is 6 and not equal to 1,2,4,8
   
   ## Impact
   Virtio Driver Config Read/Write
   
   ## Testing
   Virtio-Net with feature VIRTIO_NET_F_MAC
