| Subject: nvmet-tcp: fix maxh2cdata icresp parameter |
| |
| From: Sagi Grimberg <sagi@grimberg.me> |
| |
| 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. |
