Description
Hello I have a chassis with multiple Xilinx FPGAs. We use mcap to load the bitstreams into them. What we found though is mcap will find all the fpgas but only configure one of them as shown in your code:
We can fork and work out a solution for now but was curious if there is some use of mcap we aren't aware of that might fix this issue.

Research direction
Start in mcap/linux/mcap_lib.c at the linked query code around line 379 and inspect how multiple FPGAs are discovered and selected. Reproduce the reported chassis setup if available, then verify that MCAP can configure each discovered FPGA rather than only one.
