Subject: [PATCH v1 04/18] xprtrdma: Boost client's max slot table size to match Linux server
Date: Tue, 06 Aug 2019 11:54:07 -0400
Message-ID: <20190806155407.9529.39842.stgit@manet.1015granger.net> (raw)
In-Reply-To: <20190806155246.9529.14571.stgit@manet.1015granger.net>

I've heard rumors of an NFS/RDMA server implementation that has a
default credit limit of 1024. The client's default setting remains
at 128.
