| Subject: ibmvscsis: Add SGL limit |
| |
| From: Bryant G. Ly <bryantly@linux.vnet.ibm.com> |
| |
| commit b22bc27868e8c11fe3f00937a341b44f80b50364 upstream. |
| |
| This patch adds internal LIO sgl limit since the driver already |
| sets a max transfer limit on transport layer of 1MB to the client. |
