Having lower number of copy engine entries for target to host WMI ring is causing drops in receiving management frames. This issue is observed during max clients (128 clients) stress testing. While bursting deauthentication frames from simulated clients, approx. 70% of frames are getting dropped due to lower ring entries.

Could you explain why the value of nentries are different?
.nbytes_max = __cpu_to_le32(2048), .flags = __cpu_to_le32(CE_ATTR_FLAGS), .reserved = __cpu_to_le32(0),
