            Bug ID: 1564
           Summary: Broadcom doesn't receive network packets via RX
                    Interrupt (infinite lock rte_epoll_wait)
           Product: DPDK
           Version: 24.07
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: lucas@easy-way.app
  Target Milestone: ---

The rte_epoll_wait function is never returning, I believe that the interrupts
are not being properly configured for the bnxt_en driver after upgrade.

Bug NIC: Broadcom NetXtreme-E BCM57508

It is important to note that the same code works on Mellanox NIC, more
precisely Mellanox ConnectX-5 Ex MT28800

Steps to reproduce:
1. Update the NIC firmware using niccli utility
Download: 
https://docs.broadcom.com/docs/NXE_Linux_niccli_231.0.162.1

Command: 
./niccli -i 1 install -online

2. Change IP 67.159.40.18/24 to your network IP

3. Change IP 67.159.40.17 to your default gateway

4. Compile the code below

The final C++ code (cpp):
https://pastebin.com/VH6PLiTU

5. Run the binary generated by the previous compilation

You will see the error, if you remove rte epoll_wait the ping works normally,
but if you use rte_epoll_wait it will never return

If necessary, I can provide access to my dedicated server that uses this
specific Broadcom NIC. 

I can also provide access to the VNC console to access the server even after
starting the application.
