Subject: [SCSI] iscsi_tcp: fix header resend
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=753e7d3866748799e4a8769cd27ea7202654211b;p=mv-sheeva.git

[SCSI] iscsi_tcp: fix header resend

This patch built over the last ones fixes a bug in the partial header
resend code, where we add on another 4 bytes to the send length on the resend.
We want just the header plus digest.
