Subject: [PATCH net 6/7] net: hns3: expand buffer len for some debugfs command

The specified buffer length for three debugfs files fd_tcam, uc and tqp
is not enough for their maximum needs, so this patch fixes them.

Fixes: b5a0b70d77b9 ("net: hns3: refactor dump fd tcam of debugfs")
Fixes: 1556ea9120ff ("net: hns3: refactor dump mac list of debugfs")
Fixes: d96b0e59468d ("net: hns3: refactor dump reg of debugfs")
Signed-off-by: Guangbin Huang <huangguangbin2@...wei.com>
