Author: Gert Wollny <[email protected]> Date: Wed Mar 13 18:50:52 2019 +0100 virgl: define MAX_VERTEX_STREAMS based on availability of TF3 Since with gles hosts we lie about the GLSL feature level it is better to set the number of streams based on actual hosts capabilities. v2: Make use of feature check level to avoid regressions.
