Subject: [PATCH] RDMA/erdma: Update default EQ depth to 4096 and max_send_wr
 to 8192
References: bsc#1012628
Patch-mainline: 6.2.12
Git-commit: 6256aa9ae955d10ec73a434533ca62034eff1b76

[ Upstream commit 6256aa9ae955d10ec73a434533ca62034eff1b76 ]

Max EQ depth of hardware is 32K, the current default EQ depth is too small
for some applications, so change the default depth to 4096.
Max send WRs the hardware can support is 8K, but the driver limits the
value to 4K. Remove this limitation.

Fixes: be3cff0f242d ("RDMA/erdma: Add the hardware related definitions")
Fixes: db23ae64caac ("RDMA/erdma: Add verbs header file")
