Subject: [PATCH] mesa: add missing case in _mesa_GetTexParameterfv()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

missing case GL_REQUIRED_TEXTURE_IMAGE_UNITS_OES is required
by OES_EGL_image_external extension.

Note: This is a candidate for the stable branches.
