Subject: RDMA/cxgb3: Limit fast register size based on T3 limitations
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3026c19a14ba71ccd4dc4925abab9395ea12839c;p=linux-beck.git

RDMA/cxgb3: Limit fast register size based on T3 limitations

T3 firmware only supports one WRs worth of page list for fast register
work requests.  The driver currently allows 2 WRs worth, which
doesn't work for T3, so reduce the limit in the driver.
