Subject: [PATCH] net: hns3: expand buffer len for some debugfs command
Git-commit: c7a6e3978ea952efb107ecf511c095c3bbb2945f
Patch-mainline: v5.15
References: stable-5.14.16
[ Upstream commit c7a6e3978ea952efb107ecf511c095c3bbb2945f ]
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")
