[ Upstream commit 2b4eeeaa90617c5e37da7c804c422b4e833b87b2 ]
The server-side SMBDirect layer requires no more than 6 send SGEs The previous default of 8 causes ksmbd to fail on the SoftiWARP (siw) provider, and possibly others. Additionally, large numbers of SGEs reduces performance significantly on adapter implementations.
