If so please use either #defines > or enums with upper case names for them. These are not defined constants, but the values beg for some explanatory text why they are chosen. Windows uses, and negotiates by default, a 1364-byte maximum send size, and caps credits to 255. The other values match. BTW, the parameters are defined in MS-SMBD 3.1.1.1 but the chosen values are in behavior notes 2 and 7.
