--- Comment #1 from mkashani at nvidia.com (mkashani at nvidia.com) ---
Hi, 
Sorry for the late response,

**Root Cause**: MLX5 hardware/firmware steering on root table (group 0) has
limited support for jump actions combined with partial MAC address masks. The
bonding PMD directly passes the flow to slave ports without adaptation.

## Immediate Workarounds

### Workaround 1: Use Group 1 (Recommended)
Instead of group 0, use group 1:

```bash
flow create 2 group 1 priority 0 ingress pattern eth dst spec 01:00:00:00:00:00
dst mask 01:00:00:00:00:00 / end actions jump group 2 / end
```

First, create a catch-all rule in group 0 to reach group 1:
```bash
flow create 2 group 0 priority 1 ingress pattern eth / end actions jump group 1
/ end
```
