Packet size UHD vs libusrp2

GNU Radio

Hi,
in libusrp2 samples are sent to device in packets of 370 samples,
while in UHD now the max is 362,
is there any way to have 370 in UHD as well ?

Yes and maybe: The default recv_frame_size is the mtu of 1472 for a
maximum length udp packet. The samples per packet is directly calculated
from this number. You can increase this, however, your network card may
or may not accept frames greater than 1500 bytes.

So changing ups_per_fifo it should be possible, I will try it.
