Subject: Reduce client smbdirect max receive segment size
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3c62df55f3306238f36dc19cbe40b5e3d288d116;p=linux.git

Reduce client smbdirect max receive segment size

Reduce client smbdirect max segment receive size to 1364 to match
protocol norms. Larger buffers are unnecessary and add significant
memory overhead.
