From 0eb4d8b985be17ce39038367f222081a3aae238a Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Tue, 25 Feb 2020 16:42:27 -0800 Subject: [PATCH] nvmet-tcp: fix maxh2cdata icresp parameter commit 9cda34e37489244a8c8628617e24b2dbc8a8edad upstream. MAXH2CDATA is not zero based. Also no reason to limit ourselves to 1M transfers as we can do more easily. Make this an arbitrary limit of 16M.
