And software decryption is required when the packet was encrypted and the hardware failed to decrypt it. So, GET_RX_DESC_SWDEC() is negative does not mean that this packet is decrypted, it might just have no encryption at all. To actually see if the packet is decrypted, driver needs to further check if the hardware has successfully decrypted it, with a specific type of encryption algorithm.
